[Halo] How strong is a Spartan III compared to a Spartan II?

Obviously a spartan II in full Mjolnir is going to be a lot stronger, but how would they compare if they were both unarmored? Are the spartan IIIs worse, or are the augmentations better?

Spartan IIs and IIIs have roughly equal enhancements. Outside of their armor they’re pretty much on par in terms of raw strength and speed. The differences are primarily that the IIs were all pretty much peak humans even before they were augmented, the IIs have significantly more combat experience, and the IIs in general got access to better equipment (at least during the human-covenant war). 

The augmentation tech had advanced enough by the time they made the IIIs that they could be a little less selective. The IIIs were still great candidates, but not necessarily the absolute peak humans that the IIs were. The IIIs were also meant to be…not necessarily expendable, but much cheaper to deploy and less costly to lose. A single suit of Mjolnir armor costed as much as a full on destroyer, so they weren’t gunna hand those out to the bulk Spartans. Instead the IIIs got SPI, which was still some good armor. But it didn’t give them a boost anywhere close to what Mjolnir gave to the IIs. And the majority of the Spartan IIIs just really didn’t have a chance to reach the same level. Most of them were killed after just a handful of missions.
