Comparing the two, I like bolt. The new ver is much better than the older one, track ball movement is much improved, but not perfect yet.
I use my bb browser and managed to stay away from bolt and opera, but I do install and give them a try every few months to see if any improvements have been made. So far little improvements to get me to use them outside of a tedt drive.

Bolt is great after the new update. They fixed the scolling and navigation is a lot more tolerable now. In terms of speed, I think Bolt and Opera are about the same, both being faster than the default bb browser.
I prefer Bolt as my main browser, however, that is just personal preference. I've used opera mini and it just wasn't for me.
Bolt with the new upgrade has been awesome. Navigation still isn't as smooth as the default bb browser, but it has improved a lot. I am a sucker for speedy browsers, especially ones that can match my friend's iphone 3g
The new Bolt upgrade is great. I have both, but Bolt is much faster than Opera or the default browser. I can surf full sized websites faster than the mobile ones used to load.
