@Syst3ms agreed

@Emlightened There are plenty of people in the googology community that haven't even graduated high school yet, and have little to no experience in formal proofs. Hell, there's people who haven't even started high school. For those people, you can't start them off with something like Buccholz's OCF, where you have to actually understand the set theoretic definition in order to understand the actual function. Now, I have no idea how old MilkyWay90 is, but since he asked to learn the "easiest" OCF, I'm assuming he doesn't care too much about the set theoretic definition of the OCF, but instead he probably cares more about the actual values of the OCF. This is why UNOCF is better to learn for beginners.
