markr010001, your complaints sound very familiar. It sounds like several other people I have helped via EtreCheck reports on 10.9.
Abysmal performance & annoying bugs after upgrade points to 1 of 2 issues…
1. Apple messed up the install or upgrade of 10.9
2. Something on the system is interfering with the system
How you can leap to number 1 as 'the answer' without doing any form of testing is beyond me & defies all known troubleshooting techniques.
I don't think Apple read these threads (with over 13,000 posts for Mavericks alone why would anyone think that Apple do this?). The official "Apple community support members" post rarely in these threads.
I'd suggest you leave feedback for Apple regarding the changes you disagree with.

With respect to the performance issues, you can continue to point out why 10.8 is better, but until you post something concrete (like an EtreCheck report from any OS) it is just anecdotal evidence, sorry.
We can't help you with an OS that no longer exists.
It's a help forum, we are here to try to do that, anything else is superfluous.
