On NA it's last over 1 month average, while JP last for 6 months. NO SG ticket to trade for 40 SG Badge that let you get 1 item of choose (yeah, after 40 pull they gave one (just one), but on JP you save badge for "NEXT SG SCRATCH TO USE THIS TICKET") on SG exchange Shop. You win more SG on JP playing the 2 mobile games with your account linked (IDOLA e PSO2ES), (PSO2ES never happen on NA, and for IDOLA yeah there a localiztion happening, but its handled by a third party company and have % below 0 to have a link with NA). Its a SCAM ON NA.
You don't just get only one extra pull ever, you get the guaranteed ticket every 40 pulls you do, while also keeping everything else. Whether this is a positive or a negative kinda depends on what you want.
Keeping everything you scratched while going to the guaranteed pull is better if there were a lot of things you wanted, as you don't have to keep pulling until 40 junk/dupes. However, being able to trade for a guaranteed pull the next ticket with the recycle badges is good if you only had 1 or 2 things you wanted from the current SG scratch and you got them on the way to the guaranteed ticket, and ditto for the next one.
Also it lasts 6 months now.
