Some advantages of brushless,
Quieter operation
No need to bed in the brushes when new
Performance doesn't change with time (i.e no brush wear)
Longer motor life
More efficient so less heat
Better power to weight ratio
More granular control i.e throttle and brake
Generally cheaper

Reason to try, 
person is less likely to die from boredom :)  [just kidding]
