First, I hope this doesn't devolve into the Coleman vs Lesnar thread as in who's build would look more intimidating: Ronnie Coleman or Brock Lesnar etc etc etc.
IFBB pros generally have massive traps and necks (yokes) so are probably the most intimidating specimens to walk the earth, much more so than elite powerlifters and football players (at the same height of course so we can't consider professional strongmen except Mariusz)
But I can't say the same for the string bean crowd i.e. lifetime natural BBers. Ive seen lots of pencil necks on stage even at the national level. However, plenty natural powerlifters with near elite totals, or wrestlers generally have a yoke.
OP, do you actually WANT to be a badass (like Alpha or CT or Synergy) and accept where the physique chips fall or just want to look like say, Synergy or CT, while pursuing "quality muscle stimulation"?
