It is, unless you come from Java (using IDEs like NetBeans or Eclipse), in which case it's kind of comparable (but different). IMHO.
In fact, if MS were ever to make .NET/C# legacy like some people seem to believe "WinRT allows horribly HTML5 apps" implies, I bet JetBrains would just bolt ReSharper onto IDEA and off we all go.
if you've ever actually used Visual Studio 2010 or above, and compared it to Eclipse, you'd realize how sad Eclipse looks in comparison. I use both at work all the time. Nothing compares to VS.
I use both at work all the time, too. I tend to prefer VS, too, but there's some points where Eclipse really shines. Eclipse's continuous build, for example, is excellent. Your tests start immediately when so requested, where VS 2010 decides to first build all of the projects in the solution. Especially once the solution gets fairly sizeable, this becomes unproductive very fast. There's workarounds, but I don't want workarounds. I just want it to work immediately.
NCrunch [1] is a great help in that regard – auto-build and auto-test in the background while you work. I just wish I had codebases that were well-tested so that I could actually use it.
