If we look at new MDP1500 and it has 2% accuracy in 1:10 mode, and 150 diff volts maximum. So we have ±3 volts which is for MOSFET or IGBT  driving 20 volts signal already ±15%. Not good :/

I prefer the lower attenuation ratios, too. For me measuring a 50V signal is more likely than a 3 kV signal. Though for the really low voltage (tens of volts common mode, a few volts differential mode) there are also low-voltage differential probes like this for low voltage, higher frequency signals.
Bitstream:
On the Micsig MDP series differential probes, Micsig’s website states they “ Originated from Micsig's cutting-edge SigOFIT™ technology”. Does that mean the MDP probe head is optically connected to the box that plugs into the scope?  Or is it just Micsig being clever with wordsmithing their SigOFIT term?  Micsig has the MOIP probes that they clearly state are optically isolated, but they are about 10x the price of the MDP probes.

Has anybody done a tear down of an MDP probe?
