best jjos for learning?

i've been thinking about buying an mpc for a long time and i'm going to make that investment as soon as i have the funds

been reading upon everything mpc related. what is the best jjos to learn my way around an mpc?.. considering i've never touched an mpc

the best will be the one you stick with

................. any,but all of them

i found the easiest learning path to be:

1. JJOS free
2. JJOS1
3. JJOSXL

YMMV as usual.
