I'm wondering how long you have been around the sport? When 2 strokes first came out they were called a fad. For the record...
4 strokes ruled MX from 1924-1965 then came back in 2006-2011 46 years (give or take a few because of the time they raced together)
2 strokes...1965-2002....33 years (give or take a few because of the time they raced together)
seems like the 2 strokes have a few years to go before claiming dominance...lol
Seriously though, I like both and do not see why all the fuss about which one is better. I do wonder why when making maintenence comparisons and cost, no one ever considers the fact 2 stroke fuel cost twice as much (pre mix), or how they wear out clutches a lot faster, or how the expansion chambers are vunurable and often need to be replaced because of rock or crash damage.
