I'm talking about switch software vs ps4 software as a whole. You are always cherry picking titles to put your Nintendo games up against. Ps4 has so much more software for buyers to choose from. It makes far more sense just comparing overall software.
Here is the comparison of software sales in Japan in a comparable timeframe:
PS4 in 2014, launch in February - 2.584m
Switch in 2017, launch in March - 5.973m
