Aside from the other reasons already mentioned here, I'd like to point out that it's also the only browser that seems to have a competent 64-bit implementation for Windows at the moment. This is literally the only reason I migrated to Opera not too long ago.

I have 16gb of ram on my pc, and regularly have >100 tabs open at any given time; I may be in a weird minority of some sort, but decent x64 support really makes my life a lot easier. I still load up Chrome and Firefox when I know I'm only going to be using them for a short/quick session, but as much as I like them, they just become awfully painful to use beyond that use case for me. Unfortunately, it seems Opera is following suit with the other vendors and is probably abandoning its x64 version, but at least they were the one vendor that pursued it enough to release something usable. Waterfox and the 'official' x64 builds of Firefox crash way too much for me to even consider. I understand the hell of trying to port to a 64-bit architecture when you're reliant on tons of old 32-bit libraries and such, but I really don't like this trend of staying overly complacent in the 32-bit realm when our hardware has been capable of more for a good while now...

When I'm on Linux however: Chromium all the way!
