Best JJ OS version?

i've been doing some reading here about the JJOS and i'm still debating on making the switch or not.
i've read about people jumping around from version to version of the OS and was wondering which OS is the best 1?

just cop the free one. read up on the 1 and 2 and decide if it has stuff you want. you can even download them and test them out before you buy them, but saving is deactivated until you pay. its not something you should do much debating over. atleast start using the free one. its just like the akai os but more thoughtful. chopping is a lot faster too.

word, good lookin' out EH. i just copped OS1. so far so good.

peace...
