Magical? I always thought of it as "special"
In the same way some Olympics are... Special.
Honestly if you're on a Mac and looking for anything MORE that Text Wrangler, you're probably over-reliant on "tools" and looking to take shortcuts that will bite you in the backside in the long term. BBedit is ok, once you cut it down by disabling all the "aids" that get in the way of actually working with the code; which is to say neutering it down into being... text wrangler.
As to the other stuff mentioned so far, uselessly convoluted and needlessly bloated nonsense.
But then, I'm the guy who finds code completion an annoyance I spend more time correcting than having help, and finds the acid trip of color highlighting an illegible headache inducing mess. (which ends up broken on 99% of my PHP code anyways).
It's like all this other pointless crap -- code folding, whitespace stripping -- it's all a bunch of nonsense that if you need, there's probably something fundamentally flawed with your code.
