Other BOTW I don’t think any of the Switch exclusives are must playIt depends. IMO Nintendo exclusives are worth the console alone and also the option of being a handheld can be a big deal depending on the person. But that's not to take away from the Playstation exclusives.
The issue with the Switch is when you consider multi-plats/ third parties. I will say that I think the Switch is better for JRPG's since the handheld option makes it easier to complete these massive games. Although I am surprised that it is lacking in western RPG's.
But for all other games, Playstion is superior. Resolution and Frame Rate are obviously better, which is vital for some games. Plus you know that every multi-plat will come on PS4/5.
Personally, for me the Switch does more for me than the PS4. With that said the Switch compliments the PS4 or PC really well as a 2nd console.
