Pretty harsh words there. I'm no Apple fanboy and Mavericks works great on my 2008 Mac Pro in response to your first point.

If simply upgrading over a previously perfectly stable and working dual boot system, even after applying any software updates (other than paid for upgrades to software functional under Mountain Lion) results in nothing but problems and there's numerous threads about endless issues, including external drive corruption, it's a safe bet Mavericks is a lemon.
 
The irony is strong in this one.

This was due to faulty third party software.

Not the point. (Nice cherry picking there by the way). The drives worked in pre-Mavericks OS X, due to Apple's changes, their software didn't function as it did previously and drive corruption occurred NOT because Seagate changed something low level in the OS that caused it, because Apple did!

This doesn't mean that Seagate or WD wasn't doing something they shouldn't have been (though we don't know if that's true), and the issue should have been caught and fixed by those companies before 10.9 was released.
 
Keep seeing a lot of these threads and I just keep thinking if there even is a problem with Mavericks. I work with a lot of Macs on a day-to-day basis and have installed Mavericks many many times now even on older hardware. On any of my Macs I have never come across any problems with Mavericks. People who 'complain' about sluggish performance have stock, original old hard drives from 2007-2010 that just flat-out need to go or inadequate RAM. My clients are so happy once they experience an SSD and how their 'old' computer just became 'new' again. Old hard drives are really terrible bottlenecks.

Nice try but running off an SSD here, still had the issues mentioned.
