You cannot 'uninstall' an OSX. But there is a chance you can use the system backup you made before you chose to install Mavericks to return to your former OSX. Or you can figure out why you are one of the few having trouble with Mavericks.

etresoft  a long time contributer to Apple Support Communities wrote a very useful app he called etrecheck which helps in diagnosing many problems caused by third party installs etc.. Go to his website, read his information and from there download and run the program according to his instructions

Paste the results back here.
