Going by the comics at least,They generally don't seem to be as powerful or content as Jedi ones, and seem to 'haunt' certain locations or objects (Again, with the exception of Palpatine?) while Jedi ghosts seem to have more freedom to pop up in different places rather than where they died.
BTW although I brought it up in another thread, any thoughts on Lando and Holdo?
