I know all 2DS systems ship with exploitable firmware, but I've heard some ship with 7.1 and others ship with 6.0. I'm interested in a 6.0 system specifically because, from what I understand, you don't have to do any sketchy downgrading.
Of course, if it turns out I'm wrong and it really doesn't matter which I get, I'd like to know too.
