There's so much o like about either of them. They both have some great approaches to the engineering that I love. Giant has some great combiner ports with the locking mechanisms and I do love how the arms both have a more..."floating" vehicle design in that you can move them out of the way for better range of motion in the arms since you can just move the vehicle there out of the way. Hercules has some serious height advantag and I happen to be a big fan of the more simple robot modes as the chunk really makes the robots feel solid in hand. I also love the modular aesthetic of the weapons and how much variety you get to what you can do with them. TFC's version of Mix Master especially with all the missile pods you get to him. I find though that TFC can really fail with QC issues. The almost random ratcheting joint looseness and tightness issues. Wow those kill me sometimes XD I'm still trying to tighten up some joints on Exgraver and Mix Master while trying to loosen the sounder joint on Neckbreaker for his combined mode. Damn thing is so TIGHT. There's a few other issues too but damn he feels solid. I may want to get the Green Giant but for now I'm pretty happy with Hercules. Just needed to add Decepticon logos to him and that was it really.
