Keep in mind the .4 is 2 generations old, perfectly fine for a sportsman driver just starting out, but if you want to be competitive then the 2.1 will be worth the upgrade.
I actually still race my 48.4 I also have the 48 2.0 I don't like the 2.0 I ended going back to my 48.4 witch feels better to me and I'm faster in, also I never drove the 2.1 so I can't speak on that buggy
