The ARC option keeps things simple, so the TV volume (from the soundbar) can be controlled with the TV remote (simples).I'm not sure how it is from a sound quality perspective but I find HDMI ARC more convenient.
I have a Sony soundbar (& sub behind the telly), was about £250 (ten years ago), probably not the best there is (there is so much choice, you just have to pick one and go for it), but many times better than the TV sound.
