I purchased Superior Drummer 3 yesterday and love it.  I mainly bought it to use Tracker for drum replacement. I eventually will be learning to use all the great features available in SD3.  Is there anything EZD2 does that SD3 does not?  I can now uninstall EZD2 or maybe even sell my EZD2 license to someone?
