It's patently false that the profiling and system monitoring tools you can get on Windows are years ahead of anything you can get on a different platform. In fact, it's the opposite [1, 2]. And I wont even get into the fact that we're still catching up to 30 year old Lisp machines in the areas of editor integration, debuggers, and code assistance.
I'll take my separation + hooks for launching any day over massive integration that means doing what you want is hard / impossible.
ie, even MS's own products don't play nicely with each other. But you're more stuck with them than you would be with something more atomic and disconnected.
That's real nice for you, but what VS does is bring it out-of-the-box to everyone. Way to miss the point.
In no other creative or engineering profession is there this expectation that the most advanced tools are shrink wrapped together. Who gives a shit if you can buy paint together with your brushes? Just buy the best damn paint and brushes you can find, regardless of who sells them.
But my point stands: if you do want the fully-integrated IDE experience, VS is state-of-the-art, there's nothing like it on any other platform. That is why I don't say "better" or "worse" I say "not comparable".
