I hate point buy. I loathe it. It is the worst, most odious change to D&D since the development of THAC0 and the abandonment of proper old-school Greyhawk. It spits out either very average homogenous stats, or else allows for horrendous min/maxing with no nod to reality at all (Where did the idea come from that everyone with super strength will always have rock-bottom INT, WIS, and CHA?)
I'm not a fan of allowing inflated point-buy as a fix to that blandness either. Rolling the dice is the only true path. 4d6 drop one is and always has been the best. Not too strong, not too weak, and allowing for real-world variability. No character ends up optimal, but there's variability between members of the same class which would never occur to the min-maxers in a point-buy system.
I even resent being forced to use point-buy when building characters in Neverwinter Nights - instead, I roll up my character with real dice using the 4d6 method, and then input them via a character editor. Doesn't work for vault games, but that doesn't matter.
