I never really liked Mozilla's browser. In fact, up until a week or two ago, I mostly used IE (!) even though I had Opera 6, 7, Mozilla, K-meleon and Netscape installed (the latter one not for long, tho :-D)
But since i discovered Phoenix (thx zudo, odin ;-) ) I haven't used anything else. I like the customization options for the toolbars, which is what I found lacking in all the others (except K-meleon, which I had some other issues with).
It still has a long way to go, but I think it looks *very* promising and an Amiga port would be great, IMO.
