Opera deserves plenty of credit for being accessible to Linux users. The Opera download page provides a long list of Linux distributions for downloading the correct software package. In addition, Opera is almost always up-to-date in the Linux repositories. Google Chrome, in comparison, focuses on the "classic four" - Debian, Ubuntu, Fedora, and openSUSE on their main download page.
I've lauded the Opera browser before and last reviewed the application in June 2012. Admittedly, however, I eventually settled on Chromium in my Linux boxes and Internet Explorer 10 on my Windows 7 machine with Mozilla Firefox as my back-up browser for all my machines. For those who have never tried previous releases of Opera, Opera distinguished itself from other browsers for its heavy focus on features and its unique Presto rendering engine. I've always felt that the old Opera, with its integrated torrent utility, IRC support, and e-mail client, was for power users - which I most certainly am not. Moreover, I had problems with Opera's compatibility with the embarrassingly obscure sites I frequent.
