@ozole the thing to do is just to try it side by side with whatever your default is and then if/when you judge it good enough you can switch. That's what I did. I was using Opera and Firefox (my previous default) about 50-50 for a year or so. Once I got Opera tweaked to my satisfaction it reached a point where I could deem it superior overall to Firefox.
Previously Firefox had been my default for over a year.
