Opera has been my default browser for the past 3 or 4 years. Just before choosing Opera, I did a test on all the available browsers at the time (documented somewhere in the old Off Topic forum) and that testing led me to use Opera. Of course, some things have changed since then but as someone above mentioned, the more I use Opera, the better I like it.
You also mentioned in an above post about having high memory usage with Opera. Something does not seem quite right about that. With 10 tabs open at the present, my Opera 9.51 memery usage is a little over 130,000k which I do not think is bad considering that many active tabs.
