From my experience, ok naman yung windows 11. Been using it for 3 weeks now TS. But since i'm using 4GB ram only with i5 8th gen processor, na-feel ko talaga yung lag pero konti lang naman. I'm not that disturbed sa speed change. I adjusted it to best performance also, so medyo naging smooth siya from when i first installed it. I usually use it for online classes and creating class presentations, but if you're planning to use it on heavy stuff like editing, etc. I have no experience in those pa TS.
Personally, I love the aesthetics. Refreshing yung change of atmosphere, pati yung tones, etc. I guess it's a matter of preference TS.
