The Krogan, physically speaking, are superior in many ways to their rivals here, the Sontaren. The Krogans are bigger, stronger, have multiple organs and nervous systems, their bodies alone are highly durable, etc.

The Krogan have better armor than the Sontarens (the latter's cannot stop modern earth bullets), and also carry shields.

While the Sotoran have the advantage in tactics and dominance, they are hampered in this department by their refusal to look after the sick and wounded (which could still be capable of killing enemy troops, depending on their wounds) their belief that it is honorable to fight without armor (stupidity) the fact that many elderly Sontarens join up for military service (don't see the Krogans doing this: on average the Krogans will be relatively speaking beings around the prime of their lives), and a lack of discipline (a commander may find hismelf dueling with a subordinate if the latter disagrees with their commands. The Krogan can settle such disputes with headbutts alone, which are far less endangering than duels. Having such duels in your military can hamper your capabilities of success).

Due to these factors, I give this to the Big Bad Krogans!
