Best Javascript Debugger?

Would love to see your opinions on this subject!

I usually use Firefox's Error Console, along side the Web Developer addon. That usually takes care of a lot of the debugging as it tells me if the function is not defined, or whatnot. Hasn't failed me yet.

Testing, I'd say. Best thing to do is test all target browsers.
Then again, I don't do JS that much. I've heard good things about FF options/extensions for this as well.

I use Firebug, so it got my vote. I just think it is funny that a firefox extension is cross browser.

Firebug is undeniably the best -- it's the one I and many others recommend.

Microsoft Script Debugger requires Visual Studio or Microsoft Office, if I recall. Venkman is nice, but very intrusive, and it has issues (I've been completely unable to install it on no less than three systems; it crashed Firefox on a fourth). JSLint is just paranoid, and throws errors for minor style variations:
function myFunc()
{
}
// JSLint no like strange C-style braces! Hoorgh!Also, it's completely useless for finding logic errors (and isn't technically a debugger).

I've never tried SplineTech.
