I am using Native Instruments Komplete and Maschine as well as Logic if that is what you mean. I like some NI sounds better. I also like working with Maschine...
Especially sampling with it and using soundflower is fun.
My paid jobs like producing an album, writing jingle, scoring for a movie etc... are mostly done with only Logic so far.
It might be just a coincidence though.
It might also be that I have got used to Logic in years.
I have a sound that I'm used to for everything in Logic.
For instance the Steinway Grand I like for piano.
Mark I for Rhodes.
I really like the NI Kontakt Acoustic Bass but I always end up hiring a bass player and have him nail the bass track for acoustic standup bass...
I have been with Logic since v 2.5 or 3.5 ( I cannot remember ).
It's nice to see It has been what it is today.
I have used Pro Tools for a short while but not anymore since you can do the same bussing and routing in Logic.
We were not able to that in older versions...
