How does VS2008+ReSharper compare to IntelliJ IDEA?

I used to be a Java user, but I moved into 100% .NET 4 years ago. Having grown accustomed to ReSharper and all the commands it offers, how does it compare to IntelliJ? Both being from JetBrains, I'd imagine they are close - but I haven't used it. (I know I can do that and answer myself, but YMMV.)

Thanks;
