If you can afford the higher asking fees that come with Dolby Atmos soundbars, then it's worth investing in the tech – especially if you want to recreate a true cinematic experience when watching movies at home.
That said, if you're watching the pennies (there's a cost of living crisis on and we get it) or simply want to boost your TV's sound rather than create a high-end entertainment set-up, then you don't need Dolby Atmos to get good audio from your 'bar.
