I use both semi and pump and especially when decoying I prefer the pump because semis are restricted to 2+1 shots, pumps aren't.
and I hit double clays when shooting skeet as well as 3-4 crows in a row...
Not quite. Under the law, any shotgun that has the capacity to fire more than 3 rounds (1 in the chaber, 2 in the mag) without reloading is classed as a section 1 firearm, and so a firearms certificate is required rather than a shotgun certificate. This is true no matter what the action type is, be it semi-auto, pump, lever action or whatever other action you can think of.
