Old Or New Minecraft?

All depends no definitions on "Old" and "New".

I ASSUME, as most definitons on the subject go, we are talking about the change in attack (1.8-1.9 I think was the change?). PERSONALLY, I prefer "new". I always update (as soon as OPTIFINE releases an update... I can't stand not having Better Grass). But, to each their own, am I right?
