I have not updated yet and don't see many reasons to. (I'm also in the process of trying to switch to another DAW but can't find anything that compares to FL Studio)
I'm revisiting FL after many years of not using it (shout out to Image-Line for honoring my lifetime free updates from an FL purchase in 2009) and I'm conflicted as to whether or not I'll stick with it. The big thing for me is that recording audio into the playlist is still kind of clunky compared to other DAWs with the different Edison or playlist recording options, and the whole separate channel/instrument/playlist track thing is confusing and also clunky. It's a pain to have to add an instrument/playlist track to every channel track I add. Not being able to customize keyboard shortcuts or lock windows in place also drives me mad after years of working in Reaper (which is almost too customizable). Definitely check out Bitwig; I did a free trial and might go that route as it was really intuitive off the bat and the modulation options are insane. I also like the mixer and playlist view in Bitwig; definitely a lot less windows floating around than FL.
