I love Opera, and used it almost exclusively when I used it at all.
Sadly, it doesn't appear to be as compatible with as many websites (that I visit) as Firefox is, so when I got myself a new computer and had to choose what third-party browsers to install over IE6 (spit!), I went with FF3. The loss of Opera's general niceness was felt, but the wealth of add-ons for FF3 eased the pain a little.
IE7 can bite my buttocks.
