But then I don’t find macOS to be slow or a buggy mess, so mileage may vary.
I haven't had stability issues with any Office program in years, but everything you mentioned is moot because there are Office features (especially Power___ features in Excel) that don't have parity on MacOS. If I get a workbook from a client, I need it to run exactly the same on my machine as it does on theirs.
It's so buggy on 26, it drives me crazy. Just not nearly as crazy as Windows 11 drives me.
Besides that no problems with MacOS, it feels snappy to me and Office apps work mostly fine (except for all the missing features Microsoft refuses to add to Outlook).
Wayland per-monitor fractional scaling is delightful and after a couple gsettings tweaks restoring minimize/bottom dock I’ve been loving the polish and snappiness of Gnome. I also had to switch the WiFi backend from wpa_supplicant to iwn due to connection problems on one specific WiFi network but now it’s totally stable.
macOS multi-monitor support and scaling is a constant thorn in my side that was marginally improved by paying for Better Display. Windows 11 really is the most solid option for various monitor combinations not in Apple's happy path of resolutions/sizes.
But I don’t really like the ergonomics of using even clean de-bloated Windows as my main dev machine, so was very pleased to have such a great out-of-the-box experience trying Fedora for the first time.
