Definitely go with 12-gauge if you can. That 1/2 ounce of pellets makes a difference. I used to shoot skeet, and was pretty good at it (was AA class and got the NRA All American award). I have a Browning over/under 12-gauge with tubes that allow me to shoot 20 gauge, 28 gauge and .410.
Each step down from 12-gauge is a little more difficult. With .410 you are working with about an 9-10 inch effective pattern.
It's best to start shooting with the easiest gauge (12-gauge) then move on to more difficult guns. The recoil of 12-gauge loads isn't an issue in the typical skeet gun with a typical male shooter. With field guns, recoil often does matter.
