REPLY:

In order to achieve a wide range of impedance matching, you need to
have two of the three elements variable. Variable capacitors are
preferred by most designers over variable inductors for reasons of
cost, wider range of adjustment and availability. Aside from those
constraints, either circuit will do the job.
