Both designs have their pro's and cons...the B&M's are definitely tougher and won't bend (solid plates as opposed to fins), but the tube and fin design doesn't block as much air across it. The B&M one is also supposed to have some sort of check/bypass for cold operation (or something like that?), and is designed to not cause a drop in line pressure.
