6 one way, half dozen the other. You can purchase carbide dies for straight-walled pistol cartridges that eliminate the need for that messy case lubricant when you resize the cases. If you are using jacketed pistol bullets, there's no real need to expand the case mouth before seating the bullet, thus making pistol cartridges much easier to load (a two-step process)
If you choose to load cast lead bullets in your rifle cartridges, you'll need to flare the case mouth in order to get the cast lead bullet to start into the case correctly, making it a 3-step process - and you'll still need the case lube. You cannot get carbide dies for bottle necked rifle cases. If you neck size the cases with dies like Lee Collet-type dies, you won't need the case lube, but you would still need to flare the mouth for cast bullets.
Like I said, 6 one way, half dozen the other, but generally I find pistol cases easier to load - provided you use carbide dies.
