What's your favorite multi - editor on OS X? I was wondering if you could post your favorite code editor on OS X.

I'm looking for something lightweight (no netbeans or eclipse) for fast editing multi languages. tag highlighting and code completion highly appreciated :).

On Windows I was using Notepad++ a lot and was really satisfied with it.

btw - I don't like dashcode so much - that's why I am looking for an alternative :)
BBEdit's latest release is REALLY good. I first encountered BB way back in the day on OS7, and it was more editor than I needed at the time, and it only confused me. Since then I've become a much heavier-duty text editor user, and when they brought out a new release a couple months ago I pulled the trigger.

It's EXCELLENT. Every feature I've wanted, it's had for me, waiting to discover. Can't recommend it highly enough. You can find it on the App Store.
