Opera isn't perfect, and it seems like most of their updates are based on Scrappy Mechanics . . . but honestly, it's the only browser I've found that looks and behaves similarly to IE . . . and I liked IE - I know it was unpopular, but it suited my internet needs in ways Firefox or Chrome can't.
Unfortunately, because I use YouTube regularly everyday, and Google intentionally messes YouTube up in other browsers to get you to switch to Chrome, I had to do just that specifically for YouTube; otherwise, I still use Opera for everything else except YouTube and other video sharing sites.
