From what I've seen of most controllers in that price range they're all a bit like kids toys in terms of feel. They will probably all do much the same job, but it depends how you feel about build quality and the idea of stepping up in price. The big plus for the Arturia ones is the bundled Analog Lab which is probably the best of any in terms of bundled synths if you don't already have a selection. If you get it and they give you an Analog Lab V licence ask them for a licence for version IV too as it has about three times as many sounds as the latest version. (Apparently, they will do that). In my experience Arturia's support is a bit hit and miss though. I haven't seen the relatively new mk3 Novation Launchkey range, so can't comment on them, but most things Novation seem to be pretty much geared up for and aimed at Ableton users these days.
Having seen most of what is on offer, I passed on all the cheaper ones and even the more expensive models are all compromised in some way in the sense one will have this,but not that, the next will have that, but not this. There doesn't seem to be one that has it all for me - maybe I'm just too picky, lol.
Thanks to 2020 and all that entails I have been waiting a long time now to see the Black version of Arturia Keylab 88 in the flesh, but that is proving to be easier said than done here - local retailers have had no stock and have been claiming "new stock due in by the end of the month" since at least March, so I'm still none the wiser and as it was supposed to be a "limited edition" I'm seriously doubting that I will ever see one now. OTT for what you want, but it was the one that seemed to tick the most boxes for me.
