1996 is the best...98 may well be the worst! :p -but they both had some badassness in and around. I liked that little brazilian "sambass" thing that was going on for a couple of years...(maybe 01-03)
98 had some boom tunes for sure, real dark era with Prototype and Renegade Hardware etc the year of cutslo!
94 was sick like people have said already, bit of jungle with rolling amens and then mix it up a bit with breakbeaty hardcore of the same time with the pianos and amens fucking amazing!
