Haha, me too! 
I think seeing it on a blank system and then living with it (even just for a few hours) makes all the difference. On the blank install I didn’t have any of my files, Mail, programs, and didn’t really have to do anything - but once you do, the flaws stand out like a sore thumb. Some of it I could have lived with, but the performance regressions just made it all a bit too much to bear.
Does make me wonder how people use their Macs though… I’ll post a thread about that later 
Have you got Stats installed? Curious if you’ve noticed anything via that?
What about Spaces and/or Mission Control via Hot Corners? I’m guessing having multiple desktops via Spaces could help highlight Tahoe just feels a bit sluggish/doesn’t seem to be as efficient…
