When I started reloading many years ago my mentor told me to get Lyman dies for pistol cartridges and RCBS for rifle. At the time I didn't understand why (and he didn't explain), but after loading a ton of cast bullets in various pistol cartridges I now understand - it was because the Lyman dies came with the M-die.
Like Nueces, I've put together a couple of mixed die sets for particular purposes, however, if I were buying off-the-shelf die sets I would (and have) gotten Lyman for pistol cartridges and I've used RCBS, Lyman, and Lee die sets with satisfaction for rifle cartridges as long as I have an M-die added to the rifle sets for cast bullets.
