ABS mode, is like using real vinyl. In ABS mode if you needle drop at the beginning the song will be true to the position on the control record.
REL mode will play your file regardless what the position on the vinyl is. Load a track and it will load it at the beginning or first cue point (depending on your settings). Also, if you scratch in this mode, it won't skip if the needle does.
ABS mode is more of an emergency mode. If you need to dust your needle or clean the vinyl in a hurry.
I'd suggest you experiment with each mode and use whatever feels more confortable to you. I prefer ABS mode cause it's like using real vinyl and that's how I started.
