Which version will you buy: Dragon Quest 3 HD-2D PS5 vs Switch?

I have been trying to decide what version of the game I will buy. I love the portability of the Switch but I am a little worried that maybe the PS5 version may run at a higher fps with more graphical effects like 60fps with maybe more animations, shadows and light effects. Any idea if both versions will be very similar? Were the Switch and console versions of Octopath Traveler the same?
