50 MHz vs 72 MHz ?
I believe the HAM frequency radios are allowed to have more power than the unlicenced frequency radios... But the commercial TX's won't be any different except the frequency. (There is a level of HAM licence where you are allowed to build your own TX...)
With 50 (+) frequencies available, and generally the club fields limiting traffic to 4 to 8 (depending on the field...) aircraft in the air at a time... you'll be waiting for room on the flight line more than you'll be waiting for one of the "standard" frequencies.
