I was planning to try Reaper or FL Studio.
My biggest complaints with LMMS are: doesn’t support VST3, can’t see notes for multiple tracks at the same time (although I saw a “ghost notes” patch someone was working on for this scenario).
Unfortunately the open source DAWs don't hold a candle to any of the paid ones. But once you're paying they're all pretty solid. It's like asking if you should move to vim or emacs or jetbrains after starting with Notepad++. They're all good and everyone will have their own favorite. Many people also use multiple DAWs the same way people use multiple text editors. Personally I use Ableton and Reaper
Really, it might make the most sense to just find music similar to what I've made (or want to make), and then ask/research what they're using. Edit: I think that's how I originally found FL Studio and Reaper, come to think of it!
