I switch between Chrome and Opera most of the time, based on who's currently ahead in the speed wars. Lately I've been spending most of my time on Chrome, though, on account of a few extensions I really like. Opera is a really nice browser, though. Quick, cleanly laid out, and more broadly compatible than in years past. As an amateur web developer, I've been watching it for years and in the past year or so have come to like it enough to use it for extended periods. Chrome can be buggy sometimes, and oddly enough it hates HeadRoom's site. Opera seems to work well with just about everything I throw at it, though it does have its own weird quirks that I have to code for. For example, when I was using the old alpha transparency on my website I discovered that Opera would not render the alpha value of any element that extended beyond the current view. I had segments of my page meant to mimic glazed glass, and they didn't render until I scrolled the page down. I have no idea if Opera still does this as I migrated from the old approach to transparency ages ago, and Opera's support of CSS3 is quite robust.
