330 due to many reasons:
1. lack of binding on the fretboard: the frets on bound fingerboard Rics don't go all the way to the edge, giving you even less space.
2. It's 24 fret which tends to lead to me playing in more interesting places on the fretboard.
3. It's also more comfortable, IMO. Less sharp on the back edge
4. More resonant, better bass
5. Oh, and pointy horns.
