To crown or not to crown..that is the question..

When decorating your homes do you prefer a wall with no baseboards or crown molding? Or do you like both? Just the baseboard? Even when I wasn't playing the sims over the last several months I was still creating walls (and floors, rugs and wall stickers) and would like to share them but I'm trying to decide if I want to go through and add molding to all of the sets (well over 200 walls..bleh) or just leave them as plain walls. One thing I wish they would add is the ability to have the crown molding as a game option indoors like they have it outdoors with the exterior trims. Chair rails would be SWEET!
