Beretta has a good reputation for reliability in the clay games.
Remington is having issues these days so while the 1100 is a good shotgun, I might stay away from Remington at this time.
I do not have any experience with Benelli shotguns but they have a good reputation.
I'd think long and hard about any budget priced shotgun.
Folks who actively compete in the clay games shoot ammunition by the pallet load. For the best reliability, look to what they are shooting. Citori's and Beretta 686's are kind of the base level over/unders. Many serious competitors shoot higher priced guns but my skeet grade Citori has served me well.
Semi-auto shotguns are more price friendly than the over/unders but some brands have a better reputation for reliability than others. When I was shooting skeet competitively in the 1990's, many of the top shooters were using Beretta semi-autos in the 12 gauge events.
Finally, a pump shotgun has its purpose and in the 1930's and 1940's it was the gun of choice for skeet shooting. But today, a semi-auto or an over/under is so much better. It is nice to have the follow up shot ready to go as opposed to having to pump the gun to get it ready for the follow up shot.
That said, I use a 20 ga pump for a critter gun around my hobby farm.
I hope this gives you one person's opinion.
