It's difficult to articulate this, but I'll try. (This is veering off-topic, so I won't take it very far.)
I think, insignificant as it may seem, players like this tiny bit of randomness when going up a level. (And I do mean "tiny bit.") I know that as a player, I'm excited when I roll high HP, and disappointed when I roll low, even though we've got a minimum of half the die (rounded down).
My group ditched it years ago in our 3e games and I much prefer not having the random die rolls for hp. When I had good rolls I felt almost like I was cheating playing next to the PC who got bad rolls. And getting low rolls always sucked.
Point buy and standard hp for me all the way.
