I have both
Both have good attributes and both have bad attributes that are well documented. There are workarounds for the problems both units possess.
I bought the MS first and a Wise Precision standoff. The standoff failed at a critical time resulting in a second sensor bullet ding. Now I own a worthless bayonet and a new bayonet
I bought a Labradar while waiting on the new bayonet.Then an sd card. Then a mini tripod. Then a recoil sensor. Then an aiming device. Then an extra battery.
My biggest issue is the Labradar can't measure over 3900f/s
I still need the MS to chronograph my 204Ruger and 22-250Rem
All said and done my vote is for the MS due to cost and it's ability to measure higher velocities
