While setting up my Dolby Atmos setup, I had auditioned JBL 9.1 sound bar with wireless surround ( chargeable surround satellites ), it was around 95K, it is worth it's price.
If possible you should audition once.
Sonos is great, and the reviews are all great, but I haven't had chance to audition one.
