I know most of you will be Firefox patrons. To be fair, Firefox is awesome. But I have never taken to Firefox. I started with opera and even though few sites don’t work on it properly, I have used it consistently for the past 5 or 6 years. I used to use it back when it was paid. I loved it back then and I love it even more now 
Here is why I love opera 10:
- The Looks
- Speed dial
- The NEW sync feature which lets you sync all your bookmarks, notes etc
- This sync feature has to be mentioned TWICE. Its that good. It has a lot of features that you will love.
- Notes
- POPUP blocker is effective while still making the INTERNET enjoyable. Firefox throws up too many popups saying it blocked a popup. That’s very good, but somehow I dont feel it ever came as good as opera.
- The turbo feature is useful when I am browsing from a really slow line.
- I had always envied the Firefox users as they had the dictionary feature. Now its there in opera too.
- torrent client
- The LINK feature is awesome from a webmaster standpoint.
- Opera Mini…need I say more about why I love Opera Mini???
- Opera has always been faster that Firefox. At least for me. I just found that I was not wrong check this link
Some features that I sorely miss in Opera:
- I wish opera had an open source-code like Firefox so many more plug-ins will be released.
- Opera just doesn’t work right with some of the sites, I hope they would fox it. (Opera 10 has been working fine with some of the usual problematic sites).
- Toolbars from various sites are not made for opera. I sorely miss this. Again hopefully opera will open up more.
