OK… Here we go (as have so many before me):

Firefox: Excellent, Quick enough, Many extensions available, often updated.

Opera: Excellent, Fastest of all, Small memory footprint, full of features and easily customisable.

Flock: Brilliant, but firefox underneath (not that I’m complaining), problem is it is barely even in Beta and some stuff don’t work yet.

IE6: OK so I’m confused, but not stupid!
