Short answer: the Sennheiser Ambeo Soundbar Max. It ranks #3 of 27 all-in-one soundbars by sound quality, rated 4.0/5, at $1,699.95; the Devialet Dione ranks #6, rated 3.8/5, and costs $2,399, so there is little reason to consider the other one.
Why pick the Sennheiser Ambeo Soundbar Max: The Ambeo Max creates a big, enveloping surround bubble from one bar, with deep bass that reaches about 30 Hz without a separate sub. The tradeoff: It is very large and heavy, so it needs a sturdy stand or wall and a big TV.
What the Devialet Dione does well: The Dione delivers deep, powerful bass from a single bar, so it suits rooms with no space for a subwoofer. The tradeoff: It cannot add a subwoofer or rear speakers.
Buy the Sennheiser Ambeo Soundbar Max. It is rated higher for sound quality than the Devialet Dione and costs less, so only choose the other one for a particular feature it does better.
