Pretty much as the thread title says.

I am most reluctant on transformin' my Alternators Shockblast as it always takes a lotta time. And I really need to practice Cybertron Deluxe Unicron...

Universe Onslaught on the other hand, besides the last part with his legs is a bit annoying, fittin' those cage-like things inside.

 

my most fun is RID megatron cuz he can do so much
my least fun.... something from cybertron probably cement truck guy he's just so akward  

 

least fun: Universe Galvatron
most fun: everything else I own (I dont own any Alternators)

 

Most fun: Most of the Animated series. The transformation isn't very complex, and it isn't very simple. For most of them, the transformation is exactly as complex as I want.

Least fun: A Yamato Valkyrie. Ever transformed a $200 toy seemingly made of eggshells? Yeah...

 

Altenators were the worst, besides the engine never fitting I would always have a part fall off on me when changing.

Most fun City Commander.

 

Least fun was Alternators Optimus Prime, (Transforming Alternators sucks in general.) Movie Barricade, and Movie Ironhide. (it was an aggrivation trying to get Barricade and ironhide's legs just right when transforming them back to vehicle mode.)

MOST fun is the Classics Seeker Mold, Universe Cyclonus, Animated Grimlock, Classics Rodimus, and Beast Wars Optimus Primal (Because he has an insane amount of gimmicks.)

 

Movie Concept Bumblebee was anything but fun to transform for me.

I love transforming g2 megs, its nice to have the legends version that I can constantly transform back and forth too  

 

Most fun: Classics/universe seekers -- I just love switching the modes on these guys.

Least fun: Alot of my Alternators/Binaltech -- I can never seem to figure them out. I always have to pull out the instructions. *sighs* And Universe Galvatron -- He just kept falling apart on me.. So I'm afraid to transform him now...

 

least is altinators grimlock get stuck on the body
favourite movie crank case

 

My personal favourite at the moment is Universe Galvatron. He's an awesome figure with a brilliant transformation scheme. Whether you've got one that holds together or not is another matter entirely. I do, and he's super fun.

Least fun? Probably movie Leader Megatron. Really fiddly in the leg area, and the end result isn't much to speak of. I don't hate the figure, though, but it could have been better.

 

least fun...Movie Voyager Starscream and Thundercracker. They aren't hard or anything, i just really dislike transforming them for some reason.

most fun...universe seekers/cybertron downshift/movie grindcore

 

Most: Cybertron Downshift, Classics Seeker, Classics Grimlock, both Cybertron Hot Shots, most Animated

Least: Movie Ironhide, Movie 09 BB, Movie Barricade, Animated Prowl

 

Least: movie Blackout, and others.
Fav: this days, all the G1 minibots, classic Bumblebee too.

 

Most fun: Classics Prime mold. And/or Stampy. >>

Least fun: Classics Grimlock mold.

 

Least Fun? From my collection (started only about a year and a half ago) Movie Barricade and probably Movie Ironhide.

Most fun? I like G1 Blitzwing and Animated Ratchet

 

Least: MP Megatron. When beads of sweat form on your forehead when you're trying to transform a figure from one mode to the other, then it's no fun.

Most: Animated Prowl. It's just so cleverly designed.

 

fun:cybertron amorhide,classics mirage and fracture and energon megatron

Least fun: Amost all the alternators, universe galvatron and RID ultra magnus

 

Most: Animated

Least: Alternators

 

Most fun to transform would have to be Universe Cyclonus and Animated Grimlock.

As far as least favorite, I'd have to go with just about any Alternator/Binaltech toy. As much as I like the line, they're an absolute pain to TF.

 

Most fun is a tie between City Commander, Ani Prowl and Uni Hound

Least favorite has to be Alt Grimlock the arms are just annoying but I finally got it to an art form, Uni Ironhide is up there too getting his alt mode to fit together just right is a pain
