I don’t want to sound rude, but how old is your setup? Are you using a desktop or a laptop computer?
Because I’m daily driving a late 2015 Dell XPS 9350 and X11 just ain’t cutting it, even though the laptop is nearly a decade old. On X11, its trackpad would be garbage, GNOME’s animations would be stuttery, and fractional scaling would be a mess, because I have a docking station with a 75 Hz ultrawide monitor, meaning that I must utilise both 125% and 100% scaling factors, as well as 60 Hz and 75 Hz refresh rates and different resolutions. Sure, not everyone uses multi monitor setups, but those who do serious office tasks or content production work often cannot imagine their workflow without multiple monitors. Point is, X11 is to ancient to handle such tasks smoothly, reliably and efficiently.
Wayland, especially with a laptop and/or a multi-monitor setup. It has a proper touchpad support with 1:1 gestures and setting different scaling factors for multiple monitors with different refresh rates is a breeze.
