I'm sure in normal street driving there is a lot of room for preference. Years ago when girls would even ride with me I used to like using a "suicide" knob on the wheel so I can just hold the knob and turn the wheel as needed, keeping one hand on the girl or shifter or whatever.

But for comparison, all performance driving instructions that I ever got without exception say 10 & 2 o'clock, you only reach for the shifter when needed and then right back to the wheel, and you don't crisscross you arms when you turn more degrees than you can by keeping your hands on the wheel. Your arms should be slightly bent not straight out, though this depends on preference since some like it real cramped in (like most NASCAR drivers) while others like arms stretched out. I like sort of about a 120 deg angle at my elbow between my upper arm and forearm.
