Firefox and IE will have more compatibility than Opera because of sheer usage...

But several tech websites have done benches and Opera was much faster outright in rendering pages than both Firefox and IE. Also Opera is much more intuitive and everything you need is there without needed additional widgets and plugins and Firefox extensions.

I can't live without Opera's mouse gestures, the find in page search on page, and the zoom is amazing because it zooms everything on the page including images and video. Firefox and IE typically only zoom the text. A lot of those annoying web videos that are locked and don't have a fullscreen option can just be manually zoomed with Opera. Same with Flash games. A lot of useful buttons and totally customizable UI out of the box too. I love the hide pictures button that sits right on the corner and all the keyboard commands, etc. to make it look like I'm reading text/working when I'm at work.

But yeah, after Opera's mouse gestures and ease of use and install anywhere, I can't use anything else. It also has built in clients for transfering/downloading, bt, mail, news, etc. etc. but those don't get it in way since they aren't on by default and you don't need to use them if you don't want to. Opera can be totally usable in a complicated and comprehensive way...or utterly simple and clean and pretty if you want...all out of the small free download. No need to add anything.

Plus Opera powers the Wii!!! (although it's totally different)
