I've seen most people run on NTSC version however, are there any differences in terms of speed or glitches?
PAL is slower, PAL has slightly higher jumps and some very minor differences. Proxies are much harder on PAL according to most people. Use NTSC if at all possible, if you don't have the console emulate it. The game just runs a bit slower on PAL and it has slower load times.
PAL Version of spyro 2 has slower load times by ~1minute as well as a movement speed slightly slower than that of ntsc. There are also a few things that PAL version cannot do in runs that ntsc can (for example an out of bounds in Collosus). But overall NTSC is the way to go. However PAL jump height is slightly higher but nothing significant enough to make it better than NTSC.
