Mark bass little mark VS Phil Jones Bass M500

hi guys! i have the first version of mark bass little mark .
same sound,same watts,but yellow and 14,5lb heavy.

i'm interested to know which between the PJ and the MB2 head sounds better.
reading all around it seems a great head. i'm interested only in sound quality. i like uncoloured sound(markbass also has it).

markbass starts winner on weight, 14,5 lb VS 40 lbs!

does PJ recover and win for the sound?
