Agreed. Each looks very cool, and if there was only one to choose from, I'd probably have got it, and regardless of which, I would have been happy. In comparison, despite him being a bit smaller all over, I'm going to have to go with Giant. Holding out for the lime flavoured one, even though the lemony fresh one does look good.
I don't like some of the aesthetics of Hercules. I feel the Maketoys vehicle modes are more realistic, and more uniform, and like how the robot modes evoke G1, whilst still adding their own flair to things, whilst the TFC versions are more...experimental. Hercules does have those nice vehicle mode play features, and the options to remove cranes, shovels, etc is good, but the Giant bots are more poseable and neater robots for the most part.
The gestalt modes for each are good, but I prefer Giant's more G1 look, as well as his proportions and stability. Hercules seems very loose already. TFC giving their combined mode the better hands is fair enough, he's more expensive, but that's the only real area that I feel their gestalt is better, other than size. I can only afford one, and honestly, don't feel Hercules is worth that extra money when Giant ticks so many of the boxes I'm looking for in a Classics Devy.
