Scratching mainly, but I dunno how to describe the difference between my full size platters and my old 400 platters, mainly just feel alot more solid and precise then the smaller platter, not a great great difference but I do prefer full size, but each is their own, maybe smaller size will suit someone else oh and I should say I started on the herc RMX and software as well then upgraded to CDJ, best decision in DJing I've made, the satisfaction you get from mixing with CDJ's just doesn't compare to controllers for me man...
