tough call really, vd is that gym rat type that knows his gym but bruce is a journeyman who learns from everywhere. Bruce is the study type guy and vd is the original dude u rely on with random questions, but his passion can be a bit aggressive. His way of words can be too insulting and in the ears of the general public, he is unstable and only the ones who really know him can assure he is reliable. Bruce in the other hand gains respect with his open minded approach.

if this was about overall knowledge, vd may be street smart but bruce is a real proffessor. Bruce I.Q easily surpass most guys, thats a fact.

My point is, in each others world vd and bruce would not last but bruce would be more adaptable in most world. V.d can get frustrated and result in aggression, thats his downfall.
