Re: 300 lb Grace (not Rob Orlando)
Undoubtedly it would be the strong guy.
Honestly though (not saying that this is what you're hinting at) I'm really not interested in going down the "what is the best measure of fitness?" rabbit hole which is why I made note of the fact in my initial post that I was probably going to regret even getting involved in this thread.
I thought Spencer's Grace video was awesome (I think all of the videos that you guys post are awesome), however I also thought Dan Bailey's 1:02 Grace video was awesome. You may or may not agree. Ryan may or may not agree, and that's fine.
It comes down to what I said earlier, that your goals are your goals. Spencer, Jon, and Donny all train to support their goals. Orlando, Bailey, and Spealler train to support their's.
