Switch from Stars to Party?

Ok, so I deposited $50 into stars a few months ago and now I've worked my way up from playing the .01/.02NL tables to playing the .1/.25nl 6max tables. I currently have a bankroll of $500 and I heard that this would be a good time to move to Party. I know Party has a 20% deposit bonus, which would help, but what I'm more concerned about is the quality of the games there. How does party's $25nl games compare to stars? Are they easier, harder, about the same?
