The best place to play is everywhere, with the Nintendo Switch. So odd for them to have a tag line that perfectly plays into Nintendo's message.
I respectfully disagree. The only way Nintendo would probably be the best place to play is if they got almost all the third-party support of their competitors in addition to their first-party games, had similar specs, and a modern online and OS infrastructure. But imagine if this happened. Xbox would likely already be dead and PlayStation would be locked tightly in a battle with Nintendo.
As a handheld, Switch is unparalleled. As a home console, I don't think it matches up to the PS4.
