For sound quality and value I’d look at the Yamaha YAS 209, which comes with a wireless sub that likely will up your enjoyment factor significantly over a sound bar alone. Normally $350, for some reason it’s available on Amazon for only $220, which seems like a screaming value to me. Here’s a review...

If ATMOS is more important than sound quality I suppose you could look at the Sonos Beam (Gen 2), but it’s twice the price. Personally, I’d jump on the Yammy and enjoy the better sound quality and the extra cash in my wallet. Hope this helps and best of luck.
