Wyzo is fast, cute and functional but the last build from official site crashes permanently on flash processing.
I've found and downloaded portable version somewhere in the web - it's working stable, so testing continues...
I wouldn't like to compare Geckos with Opera in any way - they are different products with their own benefits and there is no sense to put them side by side.
Opera is unconditionally lighter than XUL Gecko's but FF is more convenient (for me), standard-compliant and extensible plus open-source.
So, KM is only Gecko compared with Opera in speed and resource saving (even better than O) but lacks some user-friendliness if spoken about average user not geeks.
