Marketing is probably a major issue for Opera. I suggest Opera and people have never heard of it most of the time, or I get a response like, "I don't want a browser that has ads in it." Opera hasn't had ads in their browser for years now. They're basically the untrusted store brand of a commodity people already receive for free.
Another issue for Opera is that 'stability' fluctuates significantly with each release.* I'm talking about how some websites will stop functioning properly. I'll try upgrading to the beta. Sometimes the site I wanted to work will work, and then it's another site that stops working. I always have to use Opera as a complementary browser. Opera will find some new way to freeze or crash as a result of a certain webpage trying to load.
*(This can be attributed to poor web design, but it's just part of the reality of being the underdog that they should pay more attention to this.)
