The former just keeps me going with Ubuntu, but forces to still dual-boot Windows for some creative software I use that Ubuntu lacks (a certain DAW and a CAD modeller). The latter gives me an awesome (or so it seems) OS that is much closer in spirit to Ubuntu than to Windows and supports everything I need, but leaves me vendor-locked to whatever user-hostile directions Apple might take in the future.
I'd like to ask people who had been using both Ubuntu and MacOS, what would you advise? And MacOS users in particular, are you happy with the direction it has been evolving, and with that of Apple itself?
