I'll be getting Earthrise because Wheeljack is my favorite character after Optimus Prime.
I have each version other than the Cyberverse 1 step.

I just completed my Prime of Every Era collection. Wheeljack is next.

 

I plan to have all three.  

 

I have the United Wheeljack i love him I'm getter ER but I'm not going to get rid of United Wheeljack

 

The only Wheeljack I currently have is TFP. I dig him. I may skip ER...still disappointed we didn't get him in Cybertronian form...

 

Currently my collection is lacking a Wheeljack, which is something I definitely need to remedy. Prime Wheeljack is going to be a must. It's my favorite design for him and although I do love G1 Wheeljack, the TFP one is my favorite incarnation of the character (I wish he had gotten more screen time).

I am undecided on the ER version. Like fschuler, I'm disappointed that we're not getting a Cybertronian one, but I must admit the ER one does look good. I am just not sure if I want to devote the money and the space to him.

 

All though, I must say, I think we can all agree that it is VERY HARD to mess up a wheeljack car mode. I think they are ALL sexy in there own way.

 

Generations and prime. Will wait on earthrise reviews.

 

I have TF Prime "Jackie" for now. Will get E.R. depending on reviews.

With a little more paint, like others have said, that CW Wheeljack could've been a better figure.

 

I have the Generations one and I really don't understand some people's attachment, its doofy:

The Prime Wheeljack is beyond amazing, but its not CHUG. You need it if you don't have it though.



CW Wheeljack is an embarrassment, it probably prevented us from getting a siege update just from its existence. NO PAINT



But Takara Wheeljack looks great....but you had to buy the whole set.... so.... $150



so yeah i'm excited about this new wheeljack:

 

Do you mind if I steal your headcanon?

 

My go to Wheeljack was the Generations red card version. But honestly, I was never 100% satisfied with him. The vehicle mode looks great but he just looks too oddly proportioned in robot mode and I was never really happy with the huge wings. Earthrise WJ looks alot better so I will most likely be upgrading to that one.

 

The Generations one is stumpy and wide, yes. Actually, very G1 toy in that way.

But the colors and paint and accessories rock. That green is sooooo nice.

 

Generations, Prime and MP. I might well replace the generations one with the ER version because I have that mold a LOT (Tracks, Road Rage, Black Tracks, Runabout, Runamuck, Marlboor / Exhaust). Actively dislike the CW version because they're cheap and so many repaints, I limited CW to G2 colours.
Also have the Energon version and the Slicer repaint, and the Galaxy Force version as Downshift and his Big Daddy repaint. Not to mention the G1 of course.

 

Even though I grew up with G1 WJ, I absolutely love TFP Jackie.
Outside of my WJ MPs, TFP is a favorite of mine.
I already preordered ER Wheeljack. He looks good in the pics we've seen, and I adore his character.

On a sidenote, am I the only one who sees the name ER Wheeljack, and laughs at the irony?
       

 

Takara United Wheeljack did a good job for me all these years but I will retire him for the upcoming Earthrise for more G1 accuracy. Still that mold and all of it's retools are damn sexy - got us a great Tracks (I know he was released first) and the Funpub toys of Runamuck/Runabout, SG Tracks (or as I prefer to call him, Road Rage).

 

Absolutely Generations... as others have said, the wrenches and details, the updated alt. mode, and to me the squat proportions actually make sense.

As far as scientists go (because that's what he is, TFP) I feel like he and (Generations) Perceptor make a really good duo like Bert and Ernie, Abbot and Costello, or Mugen and Jin (samurai champloo).

WJ's ranked:
1. Generations
2. Siege
3. combiner mold
4. TF Prime

The thing is, Iove the Prime toy, just not as WJ. I would like it better as plenty of other characters... Drift ("normal", Bayverse or RiD15), Shadow Striker (tfcc or cyberverse iteration) , or even something as off the wall as a Beast Machines Vehicon-ized Cheetor. I know Animated Cheetor happened, I'm just saying...

 

None. I'm not a fan of Wheeljack but I've always loved the G1 toy.
