Well I have to post a disclaimer first. I loathe Bose. IMO, they’re nothing but a marketing company who makes inferior audio products focused on lifestyle appeal. They use cheap junky drivers wrapped in quasi upscale design/materials.
On the other side of that, I am a fan of, and use JBL speakers in my main system, and they are on my list(as are others) for when I replace my speakers.
So the hard part is budget. In the range you’re looking at, I don’t think many SB’s will stand out from the pack. From what I’ve seen, some of the better ones will set you back closer to a grand and come with options for surround speakers. To me that’s important, but it’s not to everyone. Some of the older bars used reflective driver arrays and tech to creat Quasi surround sound, but that required the room to basically be perfect so...non starter for most people.
So as you see from the short answer, I would choose JBL. If I get a chance, I can look around and do some window shopping in the SB market and see if I like anything for 500.
