Soundbar Recommendations for Sony X9000H TV

What soundbar would you recommend?
Must have Dolby atmos and if it has google assistant that’s even better.
Currently use Samsung 320w soundbar and want to stick to sound bar only setup and no other two speakers behind the couch.
Living room is large. And couch is 5m away from tv.
Most use is streaming from Netflix and prime.
Budget can be anything from $1k-$3k. Not fussed. Happy to pay more for good quality product.
