I'm not a fan of the point buy system. Like someone else said, it makes for generic builds, where certain classes dump strength and others dump charisma and so on.
The example of the wizard with the 18 strength is a good one. It stuck with me over the years also.
I like rolling too. Fine for single player. Multiplayer needs something to equal it. endless rerolling would make it unfun. especially if you play "fair" rolling just once with players who max out as best as they can.
I'm not so big on everything being equal among the players at the table, at least philosophically. But I also understand how difficult it is to find a group where that kind of approach works. In practice, the players almost always have to be reasonably equal to keep some of them from getting upset.
Of course, that doesn't apply in a single player game, I agree.
