Reading the comments, maybe this isn't a popular opinion, but I use a lot of different ac power connectors (mostly as a sound provider) and I am glad there are several form factors to choose among. Not everything I own needs to be Neutrik Powercon... IEC works well for plenty of things, as do the locking IEC connectors. And sometimes you really need to run a 50A3φ extension cord-- which has quite different requirements than the NEMA 5-15 connectors which are common in the place I live. There are several options for that kind of power; portable 3phase distros are not cheap, but they are much better than, say, running the sound and lights for stage off a bunch of daisy chained power strips :D There are so many different usage conditions for power that wishing for fewer options triggers my Chesterton's Fence warning light.
