Any method is fine, as long as one important condition is fulfilled:
If you use feats, no PC starts with a score higher than 15.
(Rolling a 16 or 17 amounts to a free feat. Rolling an 18 amounts to two free feats. That's crazily overpowered compared to not getting these free feats. Without feats, rolling an 18 is still better than only rolling a 15, of course, but only +2 attack/damage better, not game-changer-level better)
