After more peering at Smith charts (considering matching some impedance 
to a resistance), I think there's some impedances where you can't get 
lower Q than an L match, and others where you can. There's nowhere that 
an L match gives lower Q than 3 element matching circuits.

It all depends if you are inside or outside the constant R and Y circles 
for the resistance you're aiming for.
