For the most part there is practically no difference between 10 and 11 minus changes in UI and higher HW requirements. If someone liked 10, do not see why 11 would be different. Same in theory could be said about 8.1 and 10. Most of the UI changes are better IMO, but there are some annoyances mainly related to taskbar.
I believe the only thing that many could dislike and have impact on daily work, would be the new context menu. It can be swapped to old one, but as of now there is no easy setting / toggle for that.
I like newest OS versions. Visually I do like it better as well. Kind of wish I could get back rectangular design though, not a fan of rounded corners, but that is very minor thing. When I say nothing much has changed, I mean the backend, backwards compatibility. Everything you know about Windows since 8.1 still applies + some additional features, improvements.
Do not have ads. Maybe because I am in Europe or maybe because I have Education (Same as Pro Enterprise) license or because I am using local and not MS account.
Do not care about telemetry. Have disabled most "personalization" things. I am fine with MS collecting random basic telemetry like HW inventory / SW crashes or whatever they collect.
Made a mistake about comparison. Education is comparable to Enterprise and not Pro. Have experience only for these 2 editions so no idea what's the situation with Home and Pro and if there really are ads that cannot be disabled.
I sort of want to try barebones/native experience now. Old context menu can be accessed by holding shift when needed so it does not bother me much, probably there is a simple registry fix as well if you would want to always get it by default.
For me only main initial annoyance with W11 was no seconds for clock in taskbar, but that was added some time ago so I am fine.
Previosly I used start replacement Classic Shell, but not anymore. Kind of realized I do search instead of clicking what I want anyways. Besides Win7 like start menu looking more pleasant for me, I do not care about it much anymore.
Honestly, my Win11 works well enough for my day 2 day use. I don't have to troubleshoot any random issues I may encountered in Linux (I use Nvidia). I turned off all the telemetry settings I could but let's be real, I am still using Google and all the big social media.
Win10 gave me more BSODs too. My only tip for the few Windows user here, do a fresh install instead of upgrade.
Linux desktop just ain't worth it for a gamer; when it works it's great, when it doesn't - I don't want to spend anymore of my limited time to fix or make it work.
