the 85 is utterly lifeless and without any dynamics.
The MM has its own tone, which does bear some resemblance to the EMG81, but it's a different animal overall. The recommendation is usually that it is "closer" to the EMG81 than other BKP, not that it is a "clone".
The top end is more aggressive with more harmonics and the low end is vastly superior to the EMG. The midrange is kinda similar, maybe a bit less percussive on the upper mids than the EMG.
