I use it all. on the shell shelf I have hevi-shot, remington, federal, winchester, and fiocchi. Sportsman for the rem, speed-shok and ultra-shok for the feds, dryloks and some old xpert for the winch, speed steel for the fiocchi. All of it is in different shot sizes and weights, I use whatever patterns best for what I am shooting.
Right now I'm shooting old super-x drylok 2's for medium/big ducks. I'll switch over to fiocchi 1's later when its just mallards. And I'll switch down to speed-shok 3's and 4's for hunting potholes.
My point is, shell brand does not matter to me at all. The ONLY shell I will not shoot is the xperts, only reason I still have them is I plan to shoot rabbits with them on public land. Besides those, I think any and every shell on the market is used with such good components now that they are plenty good of a shell for almost any hunting scenario. Don't worry about the brand, my suggestion is to start at the cheapest you can find and pattern it. If it patterns good, shoot it. If not, step up to the next highest price and try that one. You will save money shooting the cheap stuff and kill ducks doing so. There is nothing the ultra-shok does that a speed-shok or sportsman steel cannot, and they are (were) usually much cheaper.
Why do I shoot 3.5" for geese? Because they don't make a 4" yet!
