RiD is my favorite from those listed, but i don't really think it's underrated, i think most folks appreciate it.

I agree with the OP on it being Cybertron ~ it got pretty slagged by nature of it's relationship with Armada and Energon, but it really did have some killer, killer molds + the gimmick was fairly unobtrusive in most cases, most figures got back to a reasonable amount of articulation, The realistic-style vehicles were much more realistic ~ The different planets was a fun way to bring in a variety of styles/themes (even though the Giant planet molds were all half-baked and pretty terrible) and the Autobots finally got totally bad-@$$ with the Cybertron Defense Force and Optimus Prime (Galaxy Convoy to this day is one of my favorites to display)

Notable molds: the aforementioned Prime and CDF, Evac (one of the best helicopter molds ever), Armorhide, Hardtop, all 3 Minicon teams, Landmine, Hotshot/Excellion, Sideways (much redeemed from the garbage Armada figure), Mudflap, Vector Prime, Voyager Cybertron Starscream, Scrap Metal, Downshift, Crosswise, Primus and Soundwave/Soundblaster

 

I still think that E. Starscream is one of the best molds ever  

And Energon does have a lot of solid molds on the 'Con side, but the Autobots aside from the non-combining Ultras (which are both awesome ~ I love Landmine, one of my favorite molds ever) were just uniformly garbage. I dug them out of bins recently to catalog to sell and really couldn't believe how bad the Voyagers were ~ it would have been forgiven to me if the combined modes were awesome, but most were clunky and awkward at best (hey, just like PCCs!)

 

Ah thank you good sir!

 

These days, Alt/BT. That was the line that got me into collecting, and for a good year or two was the ONLY line I collected. It was pretty well appreciated when it was running, but Classics have supplanted it in popularity a lot since then. It's still the only truly, 100% collector-oriented line, though, and it has some wonderful figures (and a few that, sadly, haven't aged well). Bonus points for being the only line that is, for obvious reasons, all the same scale.

 

This.

 

I voted for 'other' as I was looking for either Beast Wars or Animated. 2 lines which, whilst popular, are amongst my absolute favourites and don't get the love in some quarters that they deserve.
So much character in both those, but classics etc always overshadows them. Tbh, classics pretty much seems to overshadow everything these days...

 

I say Energon. I have had quite a few figures and I have not gotten one I didn't like and I hear alot of people on here that bash the line pretty hard.

 

And I'd agree with you. If his shoulders didn't sit so high, and if his shoulderpads didn't block his bicep swivels in most poses.

 

this.

i don't really play with my alternators/binaltech either.

 

I put in a vote for Cybertron. It is clearly the best out of the Unicron Trilogy lines, but it always gets lumped in with those. I would like to give an "underappreciated" honorable mention to Machine Wars as I was almost the first vote for it. It is a sadly underappreciated line. Yes, I know they are all G2 (& G1.5) repaints with a bunch of spring-loaded basic figures, but they are so much fun and I really love the OP, Starscream, Sandstorm and Soundwave figures  

 

I voted for Generations. At least it's underrated over here. Ta, Hasbro. ¬_¬

 

I voted other. Animated Leader Bulkhead is one of my favorite figs ever. My experience is that even if they ARE cartoony, most of the figs are really good transformers!

 

i'll def. give you the first one, but the 2nd (not denying it's a problem) never bothered me ~ you could still get some wicked sword poses with him (and i like that he ~ mostly ~ actually looks like a real plane unlike the G2 mold) ~ the SuperLink 2nd version with the almost neon translucent blue is especially awesome.

 

Pretty much every toyline that's not a "Geewun update", and have a slightly different design focus to only have dedicated select as fans, not the "general public" of fans. Examples of such and why most ppl hate them are:


1. Powercore combiners - reason for hate: limbs are full of issues, all-spark blue conn., relatively little homage to Geewun.

2. Beast Wars - reason for hate: beast for alt mode for everyone instead of vehicles.

3. Animated - reason for hate: different aesthetics from Geewun. A bit cartoony. Proportions not completely widely accepted.

4. Bayformers in general - reason for hate: different aestetics from Geewun. Too alien-like. Sometimes weird leg designs.

Most of the "most disliked" lines... have aesthetics that are very different from Geewun. That in itself stems from why a line is hated, or why a line is loved.

 

Energon, and Powercore Combiners.

 

absolutely the Cybertron/Galaxy Force line.... there are one of my favorite OP and Starscream molds of all time   But I'd vote also for the Energon line that gave us excellent toys like Omega Supreme, Galvatron and the fantastic OP and Wing Saber combos  

 

Although I voted for Cybertron I consider both Energon and Cybertron underrated. Energon had awsome Decepticon molds (and a few good Autobots too) and Cybertron had awsome Autobot molds (and a few good Decepticon too). I find Machine Wars underrated because it seems like people forget one crucial thing. We got once exclusive European molds in the U.S. thanks to Machine Wars.

 

interstingly, if you cut "different from G1" from all your complaints, most of the distaste is still valid (although i think BW haters are relatively few these days, most folks think it's one of the best lines/shows ever)

 

Other, though I'm not sure which one. 

 

Yes, you are right, but you do realize that because fans mostly (myself included) love G1, our aesthetics appeal are deep down changed by it, because it is "different".

For example, Animated, I thought the proportions are dynamic and nice. But it is certainly different from every other line. And Movie? Yeah, we are used to seeing G1-ish bots.

So the reason "diff from G1" and the rest of what I stated, maybe different, but personally, I believe many of them stem from the same "root".

For the record though, these aren't my complaints, these are complaints of ppl. I collect all the lines I mentioned.
