Comparing products Ex2M vs Midi Expression

[dr_mumps]

Has anyone done or know of a comparison of the BeatBars' EX2M (or E&F2M) device versus the Audiofont MIDI Expression Quattro? Both seem fairly similar in functionality with the Audiofont unit having 4 inputs (or one for the non-Quattro version). But in terms of ease of use, sound quality, etc... any preferences?

I haven't got any experience with the Ex2M but I do have the 4 input ME iO and the single input unit. Remember that all the ME units actually accept double footswitches per trs input, so that's 8 on the Quattro or IO and 2 on the single unit... pedals obviously take up one trs input.
