I am a heavy-duty user of both PyCharm/PhpStorm and VS myself.
Thing is, Eclipse/IntelliJ plugin ecosystems are far richer and waaay more cost effective (and powerful) than VS.NET plugin ecosystems.
I know I keep pointing to Maven but Maven alone is a huge reason why .NET is left to dust.
As for 'fast' it really depends what you mean. Nobody's going to dispute that running a compiled application written in C is going to beat the pants off anything running on top of a VM, but is that speed factor important all of the time? Of course it's not. Most of the time a short wait is perfectly tolerable in exchange for the assistance in writing correct code that languages like Java can provide.
So a good programmer reinvent the wheel whenever he can?
