YMMV, I could be wrong but that's the way I remember it now. please correct me if I got it wrong.

Cone v wedge affect how much insertion and adjustment range you can have on small frames, with head tubes only about 10 cm. Makes a significant difference. Wedges are more restrictive.

I haven't seen any difference in seizing - if I grease my installations, I don't get any seizing.
