I have it and use it with a 65" Samsung Q90T, I am really enjoying it. The sound quality you get from a good movie is very immersive. Much more enveloping than the YSP-2700 I had. Sounds quite good with music as well. I am pretty picky, and I am really settling in with it. I find myself playing parts of movies just to hear how it produces sound.
Of course these things can be difficult. Hard to know what is "best" - we chase that concept quite a bit - it never ends in case you haven't figured that out. But I believe you benefit from the synergy created between the sound bar and TV (Q-Symphony), not just in sound but with potential compatability issues.
If you have specifc questions, I would happy to try and answer them if I can.
Forgot to mention, I also added a rear speaker package - highly recommended. The model I was provided was the 8500S version - they do not have upward firing speakers.
