I would go for IBrowse 2.3 any time. It's *much* faster, very stable, much better support for javascript amongst other things. It is *the* browser for AOS in my opinion.
Try to load Amigaworld as one example and try to scroll it. It will be *slooooowwwww* while IBrowse scrollt it smoothly like it shall. So does AWeb but IBrowse beats both of them in every way. It is worth the money I can tell you.
