Ableton Live, while a respected tool in music production, appears to be falling behind in terms of embracing new technologies and features.
It's more-or-less the same program (made by ex-Ableton devs), just well designed for 2023.
With that said, Ableton has the advantage of being more mature. What I mean by that, is that the stock plugins are generally better, and it has a bigger use-base, which I would argue is important if you're starting out.
If on the other hand you're a medium/advanced user, then Bitwig is a much better choice.
I think it's a case of death by a thousand cuts with Ableton. For example, Ableton does not have customisable shortcuts! Which is a huge workflow blocker.
Arguably, a lot of the issues are UX related, as opposed to feature related. But UX is a core part of the product and subsequent usability of the product.
What parts of the audio editing is weak to you? In my opinion, it's one of the strongest things it offers. I assume you're trying to edit the audio in the arranger, instead of in the clip view. What makes it so strong, is that you can chop it up in the clip view, and your audio in the arranger remains one contiguous piece of audio.
It sounds like you're either trying to use the software like Ableton and you're getting frustrated that it's not Ableton, or you don't understand how Bitwig works.
