The “figure 8” connector is certainly IEC, as is the “mouseketeer” one — which adds a ground pin offset from the middle. The latter seems to be uncommon. The argument for the figure 8 plug is that it’s substantially smaller and works well when no ground is needed (double insulated equipment) and current is modest. I have some Dell laptop supplies that use that connector, and it makes sense there.
There are quite a number of IEC connectors. The familiar 15 amp C13 model is just the most common, but there’s a 20 amp variant (horizontal blades), high temperature versions (with bumps in the inlet that prevent inserting a standard cord) and so on.
