Wait, wait, wait. When you're talking Organic generation Al, you're forcing them to pick race and class first? What the spork!? I've seen it done, and the result was 5 out of 6 characters in the party being unplayably useless characters, to say nothing of the fact that you just killed the monk, paladin and bard classes! When the wizard ended up Int 11 and the fighter was Con 8, the problem is obvious. If you're going organic, then the only way to do it is stats, then race and class, anything else is bastadry of the highest order.
I let my players pick. If they go point-buy, the get 32 points, if they're going rolled then they roll 7 sets and pick 6, arranged as they wish. Everyone then rolls their Appearance (yeah, I use it). Those who go point buy get 3/4 HP at each level after 1st, the others roll theirs, re-rolling 1s. Everyone's happy, including me.
Personally, I'll always choose point-buy. D&D is one of the only RPGs I know where the default character generation method is random (Deadlands is an exception, I don't know any others though). I want control, baby! Nor do I want a re-enactment of my first ever D&D experience, where I rolled 2 18s on the 4d6 with my Rogue, and ended up with a 14 as my lowest, while my best mate ended up with nothing above a 15 on his Barbarian, and got a 3. An extreme case, but something I'll never forget. No thanks, everyone gets an even break with point-buy, and I can easily tell if someone's cheated on char-gen.
