Grid/realign beats to a click in Live.

DJ in Traktor.
Why try to play bass on a guitar when you can just play a bass?
Traktor has better integration with dj-focussed hardware, more relevant dj functions and layout, on-the-fly looping, key detection, sample decks, auto-gain, fast collection search, playlists, sort browser any way you want ie key, tempo etc etc. If you have 1000's of tracks Live's browser is .... just not good on the fly.
What do you want to do basically? Have all your tracks load to the right place and anything be in sync when you hit play? I use Live to produce but went back to Traktor for djing, by far the best of both worlds in terms of digital convenience and actually feeling like you're djing rather than working on your pc.
If I was setting up as a gigging dj I'd get Traktor and an S4 plus maybe one of NI's smaller add-ons and be done. You can nudge/brake tempo up/down like vinyl/cd to beatmatch straight out the box and just put the time into warping really live tracks to a click and exporting in Live when you have prep time.
And whenever Traktor finally implements Live-style warping/gridding.....
