I personally recommend saving your coupons for events that would allow you to obtain more power through rebate. Cursed Hidan is very nice for sure, but it does cost quite a bit, normally around 16k coupons.
If you do need him in a team then you could go for it, but for the amount of coupons you need, you are better off using it for power! Always go for rebates!
