I default to WebStorm and sometimes CLion and Idea. I recently tried Rider as a Visual Studio Community replacement, and holy smokes, it's really fast compared to VS+R#, looks really good, and has all the other JetBrains stuff.
VS has now mostly caught up with their feature set, and the only thing I miss is namespace refactoring (which I could implement myself with Roslyn.)
Is R# just an exception, perf-wise, to their track record?
