Opera user since 2002.

The amazing thing is, I still discover new and useful features all the time. I've tried the other ones and they don't compare. Something Opera got right was the tabbed browsing experience. You'll eventually get spoiled by it. I currently have 48 tabs open and nothing slows down. In my experience, Chrome crashes past a certain point and Fire Fox slows down in general, especially when switching between tabs.

That being said, one thing you have to live with as an Opera user is that you're a minority on the Internet. Some sites don't render 100% correctly, or even outright reject the browser and require you to use a different one. Luckily, both cases are quite rare in daily browsing. Its usually the government pages or something else that is pedantic about 'security'.

The stability of the browser has also been next to none for me. For 8 years use, I would venture to say it crashes at most once a year. Some of you might say thats a lot, but keep in mind my browsing is quite 'abusive' at 40+ tabs, many of them constantly refreshing, updating or running active scripts (ie. GMail).

Give it a try!
