the 'internal' speed in Opera is much faster for me....I mean going back & forth between pages, going forward and back in a series, and refreshing. It also has very easy, intuitive hot keys...Q,A,Z,X for tabbing thru links and going forward & back...and 1 & 2 for tabbing between open tabs...left index finger does it all.

I notice no particular difference in LOADING web pages.
