They have one advantage. The hardware.They are worth it if you need one, and the space available requires one. Most are as the same quality as other kits of that brand.
"You could cut a notch in the bass hoop"???You could cut a notch in the bass hoop, or buy a bass pedal that won't hit the rim (specifically the Tama Speed Cobra.) The Speed Cobra's plate is recessed toward the player by about 3/4" and won't hit the rim.
Simply moving the pedal away from the rim is not the best solution. The problem is, it messes up the balance and timing of the beater. The beater will hit later, and at a downward angle, making it feel weird because the pedal has to be depressed further into the floor.
