All other things being equal, a new cable & or new housing could help reduce friction. That would at the very least help with making shifts feel better. New cables would do very little for worn pins & bushings though. If you actually wore it out, good job! Front derailleurs rarely get used enough to reach end of life status.
Like the others, I've also had nothing but good luck with Deore front derailleurs. Though I did learn the hard way that you've gotta use a triple for a triple crankset. The double derailleur I used had too much flex and the chain bound up between the rings and the cage occasionally. Everyone here probably already knew that.
Just adding my voice to the choir.
