The 87V has the same max resolution as the MM6000 (10pF). There is no HiRes mode for capacitance. You would have to compare display times with several capacitors of different values for fairness. It takes more time for a meter to settle on a final reading, as the capacitance increases. The 87V also warns you of a necessity to discharge a capacitor, if too high a voltage is present. I don't think the Klein Tools has that feature.
I doubt you will find a large time lag between the two meters, but it is possible.
It is a good meter, with a good collection of features for that price range and probably a top contender for the crown in that cost bracket.
The only thing I would miss is the Peak Hold feature.
