Ok , I gonna end this now with what we can ALL see to be the truth.
Groink have great arms. The deltoids and upper arms look pretty damn good but really all else is totally overshadowed by them. A lot of curlers and amateur trainer/weekend lifters like just the huge arms with poor overall development. Gronk pecs look small and a little droopy and the belly very, very big and bloated. Legs look pretty small too. Don't get me wrong, I like groink and I like very much his arms but not much else.
Bigbobs has a far superior structure, proportion and overall development. Bobs look like a true bodybuilder in the sense that he trains his whole body and aims not to have bodyparts overpower others. He is doing the hard way but it shows with his broad shoulders and nice upper chest.
Don't think I criticize groink as he has the tank top look and big arms that novice try to get but bobs look like the real bodybuilder here with all bodypart getting hit and a nice, full chest.
