i use all 3 .

decks awsome why ? you can be more agressive and more or less beat the crap outta your dance floor , love it always will.

cd j awsome agin for acuracy brilliant for effects tricks sampling etc but however you cant be agressive with them you have to treat them like a good women and be gentle and delicate ahhhh! bless.......

abelton great for perfoming your own music in a sort of semi live set anyone playing abelton with a set full of other peoples tracks dont waste my time pack your stuff and piss off outta this club.

there ya go all 3 are quality in there own way but all but 1 have a down side , which leaves me with my answer decks will always rule . but technology moves on and some of us have to bite our bottom tongue and get on with it aye!
