Is cold war the easiest zombies ever?

I've played bo1, bo3, a small bit of bo4 and bo2 and found all of them pretty difficult. Both me and the two people I play zombies with regularly have agreed that cold war is almost so easy it's boring. Cold war has some of the best wonder weapons ever, no perk limit, those field upgrades, ammo caches, armour stations and to me the easiest easter eggs I've ever done. Not to mention you can knife until round 15 I believe with the melee leveled up
