I'm for 20A recepticalss on all 20A circuits. I would spend the extra $1 or so because you are getting a better device.
Actually, you're probably getting exactly the same device. For example, I was just looking really closely at a Leviton BR-15. Inside, it actually has the same T contacts as the 20A device. On
both sides--apparently, they use the exact same mechanics for 15/120, 20/120, 15/240, and 20/240. The only difference is the extra slot in the face.
And for some really weird reason, they have the 20A/120V T-slot going half way through the back of the face of the device. But not on the opposite side, which has exactly the same contact arrangement. As best I can figure, it's designed so that you can break out the 20A T if you need to. Although, unless you're in a jam on a nuclear submarine or at the South Pole research station, I can't imagine actually doing that.
Since I have yet to see anything with a 20A plug on it, I can't see much point in installling 20A receptacles unless it's a single-point, dedicated 20A circuit. (I'm sure things with 20A plugs exist, but I've never seen one.)
