Burritos take 2-3 min in microwave, nachos are just pile on chips then push cheese squirter (20-30 seconds).
Burritos may require freezer space, nachos do not.
Nacho's have more options that are still cheap - chili etc. All usable in the pump machines.
Unit price of nacho's are much less than burritos and have greater markup.
People will actually eat nacho's.
