To be honest, I gave up on all those sort of things a long time ago. There was an add in for VC6 that was essential, but most of it's features got put into VS 2002, and after that, whatever I tried, added nothing I actually got into the habit of using, and they ALL made my system more unstable than it already was. I am sure that CodeRush was one I liked for a bit, and got rid of because it slowed my system down. VS has enough bugs, without adding more, IMO.
