Bolt vs Opera mini

These 2 mobile internet browsers are both very good (way much better than your phone’s original web browser). But the question is, which 1 is better?

Personally i use mostly Opera mini. Even i have both browsers on my phone..

what’s + in Opera mini?
*It can be very fast (depends on your phone)
*You can change the skin colour
*You can browse the internet in mobile mode or desktop mode
*the screen can be flipped

what’s + in Bolt?
*it’s fast too (not as fast as opera)
*you can copy any text you want.
*any pictures can be saved
*youtube videos can be watched directly on youtube.

– in opera mini
*slow download speed.
*you can’t browse when downloading a file.
*sometimes it duplicates any comment you’re making
*some sites can’t be browsed

– in Bolt
*slow download speed
*can not browse while downloading
*sometime stucks when trying to go back to the previous site
