If you put the cost aspect aside. Multiple blades means that it is easier to shave. Single blade means all the pressure you put on the blade is going through one sharp blade to your face. Multiple blades means the pressure is dispersed over the multiple blades. 3 seems to be the sweet spot for me.
So, if you were willing to be extra careful, then shave with one blade. If you need to just get it done, multiple blades.
