I seat and crimp as separate operations. All my reloading these days is done on a turret press or a progressive, so it works well for me. If I were loading for a revolver, and using a single stage press, I'd most likely seat and crimp in one operation, as I did for 30 yrs or so before the LFCD. Crimping as a separate operation with the LFCD insures my loaded rds will chamber using mixed range brass. I use it on everything I load, including revolver ammo. As your ammo is working for you, I wouldn't change anything.
