I am very confortable with either weapon, having shot both extensively in competition. However, If you are a very casual shooter, with little interest in shooting and maintance of your weapon then the nod goes to the revolver. But one thing no one metioned is what state of readiness do want this gun to be kept it, and do you have small kids or other unathorized people comming into your home.
I keep a well used and trusted series 70 Colt 1911 for my bed side gun, for two reasons, one is I have found that I am too fast with a loaded revolver, to keep one at arms reach at night, I keep the 1911 in condition 3 at night, this slows me down just enough to keep me from firing before I have had a even a second to think espacally if startled. The other is during the day, it is hidden, with the clip left slightly low, requiring a tap, rack, bang to fire. This is what I feel confortable with. If I lived by myself, then I might keep the revolver handy instead or in addition.
