It just depends on application compatibility and to a smaller extent driver support, though that shouldn’t be a problem for an older laptop.
I haven't even tried windows 11 even though my PC is compatible.
Went full Linux and I'm not sure what I was missing at this point that I needed from Windows.
Ran Pop OS (cosmic) which is the new Wayland based one but unfortunately it's still buggy and then I switched to a gaming focused Linux called Bazzite which has been perfect.
Tiny learning curve because it's an "immutable" OS but have everything I need running on it plus everything gaming related works out of the box.
If Linux supported all the games I wanted to play, I would ditch Windows on my home PC.
But Firefox on Ubuntu is not very good. It can expand to fill the whole machine and get killed by the OOM killer. Sometimes during long text input it hangs and has to be killed and restarted. 8 GB isn't enough any more.
