What is the best Web Development IDE for OS X (that is comparable to Visual Studio)?

Question

I'm trying to find a good Web Development IDE for OS X Yosemite. And I've just run out of things to search for, so now I'm asking you - do you know of any that compare to Visual Studio on Windows?

---

• Specifically, I'm looking for a native application (natively-built, that is - not some Java-based crap or a web app disguised as a normal app);

• Code Completion, (very similar, if not the same as Intellisense in Visual Studio);

• Lots and lots of features! Build features, debug features, breakpoints, refactoring, unit testing (optional);
• Multiple language support - and preferably .NET-based language support, too (if you're going to suggest Mono or MonoDevelop, please also suggest an alternative to that).

Syntax highlighting is of least importance to me at this point. I am really struggling to find a descent IDE for OS X.

Ideally this IDE would have support for C# (a must), Ruby on Rails, PHP (a must), and (probably wishful thinking) some kind of support for Windows Azure deployment.

I have tried many IDE's on OS X - including PHPStorm and Web Storm however I can't even get those to work, despite having installed all dependencies.

_Also, if anybody knows how to use Xcode 6.X for Web Development (in any language), that would just make my day.

A simple Google search gets this result:

August 2014: I streamlined this tutorial to make it even easier to set up your development environment. I’ve archived the original version. This version works with OS X Yosemite (10.10), or Mavericks (10.9) and uses Homebrew instead of MacPorts as a package manager.

• Why Not Just Use MAMP?

MAMP is a package that will install MySQL, PHP, and Apache on your Mac all with one download, and a quick install ...

• Xcode

First, you need to have Xcode (Apple’s development bundle) installed for a few of these tools to work. You can get by without it if you try really hard, but if you’re a developer, you’re probably going to need to have it at some point. It’s massive, so start downloading it now. Grab it from the App Store, and then grab a coffee or play with your kid or dog ...

... and so long.
