I think that the main reason flatter is better is because all of us have learned using flat Firebirds. A flat Firebird is ridiculously overstable and of great utility. No other disc flies (or doesn't fly) quite like it. I think the domier Firebird has more glide and less HSS and tends to overlap with other faster, overstable, long range drivers. The dome also gets bullied by the wind a little more and is less forgiving for ugly forehand OAT.
So the domey Firebird is a fine disc, its just not the same disc we have come to love and trust.
