The main problem I have with Opera is that my first user experience was one of abject confusion ;)

The UI is really cluttered in terms of all the different bars and buttons that I didn't quite know what to do with.

Chrome just feels nice. There are some tabs, theres an address bar, and there is a back/forward and reload. I think there are other features too, I just don't see them ;)

I get rid of everything except the address bar. Previously I didn't even have that showing most of the time, as there was a keyboard shortcut to hide and show it (which has since been removed).

Once you've taken away all the clutter, Firefox, Opera, and Chrome all look quite similar (you can't remove much from IE7). Chrome is still the fastest by a huge margin, which is why I'll probably start using it on Windows.

Yah, as a first time user though, I wasn't sure how to get stuff back after I hid it unfortunately.

I got used to it after awhile though, so I guess it was okay.
