The most fair thing is to make a comparison of the first two weeks of each version. In that sense, the version of Switch = 46k, PS4 = 287 k, Xbox one = 126K.
Most of the time, the PS4 and XBOX ONE versions have been priced at 20/30 dollars. It will be interesting to see if Bethesda does the same with the Switch version, since neither the Doom and Skyrim Switch versions have had significant price reductions in the retailers.
Switch Friend Code = 5965 - 4586 - 6484
