If I'm interested in dealing damage, I'm going to be a fighter-type. As a fighter-type, I will usually hit what I swing at (full BAB, baby!). If I usually hit what I swing at anyway, jacking that +1 into my to-hit roll is a pointless 5% difference. Jacking that +2 into my damage roll, however, is a 20% bonus (on a d10; almost on a 2d6 or a d12).
It's nice to hit what I'm swinging for, but if I do that anyway, I'm all about the damage.
If I was a wizard or cleric or monk or rogue or something and I was for some reason interested in being more combat effective (for some reason), the +1 to hit would almost always win out, however. But that would be almost playing against type anyway.
