Hmmmm if its just between the blues pro and the BBD, i would take the blues pro because it has a grittier, fatter and a TS tone on steroids character without alot of mid hump with lots of gain on tap compared to the BBD that is smoother, more tweakable and cleaner in some sense with lesser gain.
But be warned that it is totally untrue that the blues pro or BBD has no mids at all cause the mids are still there but just not as much as a TS9/808. If u r looking for the so called "transparent" OD tone, i think it is quite hard cause after all both r TS clones.....
So u gotta know what u r looking for, cause they r both different animals! Personally i would choose Barber OD pedals over both pedals mentioned.
