The last feature that made me reinstall ReSharper was smart completion. Although by now IntelliCode seems to be often on par with it (plus some extras like automatically recognizing manual refactorings and offering them as actual refactorings). As for refactorings and analyses: Roslynator is quite nice, but requires some tweaking which rules you really want enabled because it will otherwise cause lag as well.
