No love for iron? Iron > Chrome by far. Iron flattens chrome. I use iron primarily now.
On my wondows box, I used to use firefox 3.6, but now that they've dropped support, opera is my backup. I used to use opera primarily ('cause it's awesome!) but it can't handle my browsing habits that well (500+ tabs open: Memory HOG!)
I use midori a lot, too, if I just want something quick, and another browser is in use. No flash in windows, though. I wish midori were a little more predictable/stable.
Ofcourse, I try to get away with using links2 or links hacked, but there's just so much javascript and graphical content online nowadays.

Palemoon looks pretty decent, I think I'll try it next. I really despise Fierfox's (and chrome's) release schedule. Why don't they just add +5 to their version number every couple years
Technically, I still use iceweasel 3.6 on my linux machine, but that's really because iron doesn't want to load any page with a # in the URL, so I'm using it for GH at the moment.
I haven't heard of "Iuakit" before, and am looking it up now.
