Autos are easier to clean hands down, revolvers have got lots of nooks and crannies for various forms of crud to accumulate. I've got 6 of each, and the autos are much easier to clean up. Stainless revolvers show up more soot etc. and actually take more time to clean up than a blued one, if you want to it spotless. Revolvers shooting lead bullets are more likely to build up lead in the barrel, which is an additional cleaning step. 22 revolvers get more crudded-up because the ammo is dirtier. On the other hand, once you get to cleaning anything, it's just a matter of how much time you want to spend.
