I installed Tahoe on my desktop and laptop the day it came out. I really stopped noticing it after the first day or two, there aren't a lot of places that have overwhelming, liquid glassy-blur/transparency on macOS that you run into often. I think the only time I'm reminded that Liquid Glass is "a thing" is in the Apple Music app where they went ham with it.
I have Tahoe on my personal laptop and the previous release on my work one and tbh I hardly notice any of the differences. It's more noticeable on the iphone where the system UI takes up more of the screen but on the mac it's 99% just the same full screen apps you always had.
