Reply to i love traktor, just bought new CDJ's.. do i really need to switch to rekordbox?

So here it is, I just bought a new setup, 2x CDJ-2000nexus + 1x DJM-900nexus.. I've been using Traktor 2 Pro for several years now, and really like how close of a zoom you can get to the waveform when setting beatgrids.. I tried installing the "rekordbox" software, and was really disappointed that I could hardly see if I was being "exact" enough when moving around the beatgrids..

In using Traktor, I am basically a pro at quickly and efficiently setting beatgrids.. Is there any good reason why I should switch to rekordbox (like will I lose any important functionality of my new setup?) or will Traktor do everything that rekordbox can do plus more?

And also, do Traktor beatgrids transfer perfectly on a USB drive when I plug it into my CDJ's? Thanks for the help!
