Doesn't matter which region you choose. All games are mostly region free now. Personal advice go for the newer batch models. Those that were manufactured in jan 2014 onwards, lessor chance of any defect(BLOD).
I have region a 2 jap. Works great, oh one thing to keep in mind reg 3 has X and O buttons inverted. But personally would go for a reg 1, the guy from whom i bought ps4 was out of reg 1 consoles. Had already wired the money so got reg 2 instead. Oh and region 3 are cheaper of course..
