deagle scope vs. ak knive

hi guys ,
i am going to buy buy 110k zp on aaturday . a already have kriss , 2 m4 c and 2 ak scopes and im not interested in m60 or rpk crates . So i think i will buy ak kinive or deagle scope crates.
Now my questions :

1.) Which weapon would you prefer ?
2.) Do both crates give on average the same amount of coupons ?

btw I already have every other version of the ak 47 , but no specail version of the deagle ( no luck in 550 deagle c crates ).

thank you for all answers
