go - Any difference in using an empty interface or an empty struct as a map's value?

Question

I am using this construct to simulate a set

type MyType uint8
map[MyType]interface{}

I then add in all my keys and map them to nil.

I've learnt that it is also possible to use

map[MyType]struct{}

Any benefits of using the empty struct versus interface{}.
