First, you have to check if all the software you use is Mavericks compatible. Then you need to see if the issues people are reporting apply to what you are doing.
I ran in to a few things I didn't like on Mavericks and went back to Mountain Lion from my backup. Hopefully Apple will fix the issues soon. One of the issues is the new version of iWork is missing a lot of features. Another is iBooks doesn't allow you to edit metadata and it forced re-downloads of all purchased books the first time it was run, some with very bad metadata.
Other than the issues I ran into, memory management on Mavericks does seem to work as advertised and is a nice improvement.
