I like the way you framed the question, and I'll go out on a limb and say that college coaches like both - but what they look for is bat speed and a good, hands to the ball approach.
Ditto to jp24's response on hands and bat speed. I'd add someone who is coachable, and has some degree of foot speed that has the potential to take that extra base.
As a recruit, I'd look to a hitting coach who gets results. How many of his current players hit above .300 or hit for power or both. My wife and I were at a midweek D1 game (A10 vs ACC) last week where we know a lot of the players. The A10 team's lineup had 8 of 9 starters hitting over .300. Their results and approach was impressive. They were kept at bay by the starter (lefty off speed pitcher), but then they really starting getting aggressive. They put on a hitting clinic.
