I have seem more Nintendo fans going on calling it one or the other depend on the situation to defend Switch (like if it could have all the positives from both sides but no negatives) than Sony or MS fans to criticize it. It is necessary to accept that it being hybrid it have the pro and cons of both and depending on what you like to play one will outweight the other to you.
People see what they want to see, and seem to be willing to say anything to fit their argument. What a surprise right? Now if you ask, if there are Nintendo fans that say that, then they are just as wrong as Sony fans claiming it to be one or the other. The correct answer is listen to Nintendo themselves. It is a home console that can be taken on the go, simple as that. It is in competition with the PS4, no matter how it is positioned. At the end of the day, it is in competition for the consumers playtime.
