I installed Arch on my old Mac few months ago, alongside Xorg and i3, they were what I was used to before I switched to Mac about 6 years ago. Back then Wayland was a mess, so I never even bothered to check it out this time.
However, few days ago my non-technical girlfriend wanted to use my laptop, I couldn't see her using i3 so I decided to install Plasma, a proper desktop environment. Lo and behold I couldn't launch it. After searching I found out I needed plasma-x11-session as the default plasma install now included just a Wayland session. I found this a bit surprising, so I did further digging and discovered a huge chunk of Linux desktop community have basically migrated to Wayland since the last time I was here. Very surprising I must say.
So I decided to try Wayland again; I installed Sway and was pleasantly surprised. My screen resolution was automatically calibrated, operations seemed to run more smoothly, my laptop's fan kicked in less frequently (don't know why), and I didn't need a compositor package to fix screen tear (bye Picom). But all these weren't the reasons I decided to stick with Wayland. You see, in x11 I've been having a persistent problem: playing videos from certain websites, notably Twitter, introduces noticeable flickers. I tried everything to get rid of this: media drivers, verifying GPU acceleration, calibrating refresh rates, nothing worked. When I installed Sway I decided to see if this issue got magically fixed, and lo! It was. Wayland has come a long way since I last tried it. Now that I mentioned it, I have just remembered I need to figure out a way to share screens on Google meets, at the moment I seem to be limited to sharing just the Chrome window.
I recently had opposite experience - I been using NixOS with X11+i3 for about 2 years and never had any significant issues beside some troubles with one Nvidia driver version, even most Steam games worked for me without any issues. But out of curiosity decided to give try Wayland+Sway. First Sway remind me that Nvidia GPU completely unsupported and probably wont work at all, but in really fix for that just to use some 'unsupported' flag to launch it. After that I found that displays fractional scaling only can multiply original resolution to bigger size so is no way I will able to set up my 3 different displays in way I would like. Then I found that Zoom app can't share display even if everything for that is provided and it thinks that sharing actually happen (it can share if used thought web-browser and it also some workaround with virtual camera thought kernel module and OBS). After that I found that Barrier app (that I been used to share cursor/keyboard between desktop&laptop) while has support for wayland it can't work with Sway yet and is no any real alternative.
For now I can deal with that stuff but it looks like more I use wayland more issues I see so not sure that I will able stick with it long term.
oh now I also has flickers with discord app
