I agree with you. While Snow Leopard improved on some things, some other things felt like I just downgraded.
I just went back to Leopard after using SL since launch. My personal USB boot key died so I've been back to the managed Leopard install on the work laptop. I'm curious what felt like a downgrade, because going back to Leopard for me has been painful. I don't drive my machine that hard though, really... the web browser and XCode get a workout, and I do a fair amount of H.264 screen capture. Other than that I'm largely sshing to remote SUSE servers for good old C/Perl/Ruby coding. I've noticed in particular that SL *greatly* improved stability with anything movie-related.
