I know a lot of people who like resharper, but I'm a CodeRush guy myself. I've evaluated both and CodeRush has a much better UI (no modal dialog boxes) and does some awesome stuff with graphics so you can preview what your code will look like after a refactoring. It has had some mem/perf issues in the past, but they have fixed their issues - the same can't be said for resharper.
