I was mainly using OS/2 until its EoL (on IBM).
In the period, I've tried several OS'es. #FreeBSD (since 2.x), #BeOS, #Linux (Yggdrasil, Vine, and maybe Turbo), #超漢字 (an proprietary implementation of #BTRON) and WinNT.
When OS/2 by IBM was EoL'ed, I needed to decide which OS to move on.
At the moment, BeOS and 超漢字 already (actually) stopped upgrading (Now Haiku is available as a successor of BeOS), so both are dropped, although both had implessive performance.
And I disliked the configuration styles of Linux distros and WinNT, so FreeBSD won the race for me.
And I prefer X over Wayland at least for now. AFAIK, there is no usable (for me) magnifier like one #compiz Mag plugin. So I stopped investigating Wayland, maybe until compiz 8.x series and #Mate DE supports it.
