I think both of them are very similar, almost identical in every department, except that the V30 camera is more geared towards video (so it's good for those video enthusiasts) while mate pro is more towards stills.
for me i'm going for pro because of the poor front camera of the V30 and I am not into videos. more likely that I use the front camera.
