Reply to beginner software

Hey guys
So I just ordered a Mixtrack Pro
https://www.storedj.com.au/products/NUM-MIXTRACKPRO
and it says it comes with
Software including Traktor LE, Serato Intro and Virtual DJ
Which software would you recommend? if you could state why you like it and why not would be sweet!
can I use software like Traktor 2 with a mixtrack pro ? , and Also with Traktor scratch does it allow you to mix music aswell?
thanks boys! , I know its a lot
