Now I want to see which version of Doom Eternal will sell better: the one on the Switch or the one on the XBOne?
The one on Xbox One. While other genres like platformers or action adventures and especially RPGs do comparatively well on Switch, the shooters released so far are not the best sellers. That means Doom and Wolfenstein in the first place. As Doom Eternal will not be a late port (I hope), it might do a bit better, but I doubt it coming near XB1 numbers.
