I know there are 2873 threads about this, but is there any consensus on what the best AA/AAA powered headlight is?

I have a Serfas SL-200, which is good enough for being seen, & for reflecting off of street signs, but not so much for anything else.

Everyone seems to agree that Planet Bike SuperFlashes are the best taillight (and I have TWO of them), but is there a headlight that is equally agreeable?
