Prowl: Well, now that I have him in hand, I'm pretty pleased with him. I like the sparse deco and the transformation is an interesting take on the original G1 Prowl transform (in that it's not a direct rip of the original transform, but achieves pretty much the same look of the G1 design). Also, I like the sparse deco. The only two things that I wish had been done differently are:
The shoulder launchers - I wish they had been either molded in gray plastic or painted. Not a big deal though, as I fold them down for the G1 toon look.
The feet - I wish the flip-out heels were a bit longer. As they are right now, it's hard to keep him properly balanced. Unless he's posed juuuuuust right, he tends to fall over.
And also, his head does sit up a bit. Kinda funny looking, but nothing horrible. I find that if you push the car roof up a little bit it offsets it.
Sunstreaker: 
and

A great figure. The best of the three new deluxes, hands down. I can't wait for the Sideswipe retool.

The "Sideswipe" transformation (yeah, the hands aren't swapped I know)
Octane: My least favorite of the three, and probably my least favorite Classics TF overall. Man, when I first opened him, I completely hated him and almost took him back to TRU. My opinion of him has softened somewhat, but my main gripes are:
1. Three Half Assed Modes! The best one is the Jet. The tanker truck is worthless if you have carpeted floors. I expect to see a lot of these with broken propellers in the future (ya know, if kids actually play with it.)
2. WTF his head doesn't come up all the way 
Seriously. I know there are fixes for this, and I tried one of them. I'm not willing to slice up my fingers to get his chin to clear his chest (I think I may have raised his head a little, but only as much as safety would allow). Unlike the easy fix of Animated Bumblebee's stingers (just keep whittling away at excess plastic), there isn't enough clearance to get an exacto knife in there without either cutting your fingers, breaking the entire assembly, or accidentally mangling the head.
3. The hands. Okay, okay. I understand that they need to form another part of one of the alt. modes. Cool, you molded in hand details, but really...molded details don't do any good if they don't stand out. A little silver paint goes a long way, Hasbro.
4. That shield/claw thingy. Really, what's the deal with all these obtrusive claw-spinny-things? First on the Classics 2 pack Megatron, and now one for Octane? At least you had the good sense to keep it as a removable item.
Now, with all that said, I've done as much as I can to "turn that frown upside down". I did what I could w/the head, and found an alternate transform for the arms so they aren't so high up.
Alt. transform:


The original way.

Yeah, he's not my favorite, but I do like him more with the alternate arm transformation. Honestly, if it weren't for that I would have probably gone ahead and returned him. I still can't understand how people think this guy is better than Classics Astrotrain. Personally, I like Astrotrain better - decent shuttle mode, okay train mode and a solid bot mode. Octane
does have a better colorscheme though
