MOFO 15 won't stand a chance... it's hella inefficient, doesn't have a whole lot of excursion potential (it will bottom out after a relatively short distance, if you can get enough power to move it anywhere), and the glue joints pretty much ****. Yep, all from personal experience with the driver.
Of course it costs like 1/3 or less than a XXX 15 so I don't really understand why the comparison is being made.
