When Win11 first released, the idiot I was (or maybe still am) decided to install it on my ancient laptop because it was the newest one. It had a 6th gen i3, 4GB of memory, and 128GB storage. Didn't have TPM 2.0, so I found a workaround (forgot what it was but I did) and when I installed it, it CHUGGED.
I even installed Unity on the thing because I liked game development, and when I tried to mouse click while it was running, it took a good half a minute to register (and I somehow put up with this for like a couple years). Even without Unity, I remember the battery life being a lot worse and simple apps took ages to load.
Once I got a new laptop and learned that Linux isn't voodoo computer magic and had a usable GUI, I installed Mint on my old laptop to try it out, and it was FAST. Gone were long load times. The battery at this point had completely died so it only powers on when connected to the wall, but the laptop felt like it was new again. The screen was still garbage so I wouldn't use it as my daily driver, I much prefer my current laptop. If I ever got a new laptop, I would definitely install Linux again. (honestly I'm just not bothered to re-setup everything on Linux and backup all my data and settings and such on my current laptop, don't think I have a thumb drive large enough to back up everything)
