I have a 0200 and prefer my 0301 and 0302.
B2Q6 is right, the 03XX line is quite a bit different than the 0200 for all the reasons he named, plus S30V verses 154CM steel. Personally; I think the 0300 is more comfortable in-hand and is a bit more of a beast, which I like. I also prefer the SpeedSafe and titanium framelock on the 03XX series. They both use the same thickness blade stock, but the 0200 is a bit thinner ground toward the tip and has just a bit longer blade. In use, you hardly notice the difference in length, but the tip on the 0300 definitely strikes me as stronger.
