Simca, have you tried Maxthon browser for Android?
I doubt it's going to bump you at all from using Opera (which I've tried, and it's quite good actually - except for the fact that it rearranges webpages in a very annoying manner. You should see how OCN looks on Opera mobile...). But lately, I started using Maxthon. Not only does it take up less space, but it uses a lot less RAM, important on the limited 256MB of the Milestone/Droid. The thing I like best about it though I'd say is the UI & gestures functionality, and the style with the grey theme
May be worth a try.
It actually ranks second on
this list behind Opera Mini (which has Opera servers compress data before getting to your phone - interesting but firstly I would never trust my web browsing data going through other servers before my own, secondly I'd hate to have things such as image quality sacrificed, and thirdly I don't have 3G data enabled on my phone anyway since I don't have a plan for it)
