Wats better akimbo usps is spas grip ( mw2)?

Idk wat to use as a secondary the akimbo usps ( they r a little more impressive to see ppl get owned by ) or the spas ( wich works good but is less impressive ) they are both good but wat works better for a non rushing cl ( my primary is scar extended mags , perks : scavenger pro , stoping power pro , last stand pro or comando pro)
