Seriously though, it's all about the games you like. If you're into RPGs like I am, PS4 has games like Persona 5 and Final Fantasy 15, while the Switch will have Project Octopath Traveler and the new Fire Emblem game. Both will have Dragon Quest 11, Disgaea 5, and Kingdom Hearts 3(possibly switch on this one) anyway. There's also games like Metal Gear Solid 5, The Witcher 3, Uncharted 4, and Grand Theft Auto 5 for the PS4, while the Switch has Breath of the Wild and Super Mario Odyssey. Look into the games, man.
