Seems like a perfectly viable and good looking primary option to me. Looks really good and no, they should not have aimed for 30 fps. Honestly without the PS4 version running right next to it, even docked mode will look good in action.
The PS4 version definitely does look better overall, but for those who would like the option of portability the Switch version is a good version to have as well. All depends on the needs of the gamer. I for one, will be buying the Switch version.
