5.56 is a higher pressure cartridge but it's close enough that the two may recoil the same, depending on other factors like gas port size - 5.56 needs a smaller gas port, but some 5.56 AKs are overgassed - and recoil spring stiffness.
If I put my two current 5.56s next to each other while shooting, for example, the Saiga .223 has noticably more recoil than the Bulgarian 5.56 74 I built. I used a small gas port on the Bulgarian while the Saiga has a larger port and is somewhat overgassed, which can be corrected with an XP recoil spring. Otherwise the two rifles are identical, with 74/100 series lightened internals, both have Bulgarian AK-74 muzzle device, and so on. They are basically the same rifle but one recoils harder.
Whereas all 74s more or less will have the same exact gas port size.
