essentially camino is firefox (gecko engine) built to use mac osx specific tool kits and optimizations. safari is a mac product that resulted from the joint venture between the KDE dev team and Apple to improve Konqueror (speficifically the KHTML engine). Personally I hate konqueror (its ugly and slow), and am currently using firefox accross the board on all my windows, linux, and mac machines, or at least i used to, till my school blocked the use of firefox but not camino, so i am back on camino. its nicer than safari i think, but because it lacks many of hte features (extensions specifically) that the barebones firefox does have...kinda kills the fun for me.
