Unique works well in all of those applications, including .357 mag which is the most different of the bunch. Each probably has its own favorite if you want to squeeze the last drop of performance out of them, but hey, you're just getting started! There's plenty of time to fine tune, and spend lots of money on multiple powders later, after you get started and figure out what you are doing. Don't get bogged down looking for ultimate optimum load in your first batch of ammo.
