Looking back at the graphical comparisons, I really REALLY hope that they iron out the lighting effects on the Switch version of BotW. As is, I much prefer the moodier lighting on the Wii U (Although I like everything else more on the switch)
I highly suspect that the WiiU version is going to end up looking a lot more like the Switch version than a lot of people are suspecting. I think the truth is, we've only seen older WiiU footage, and that the Switch footage we've seen has all been of a newer build that has tweaked several visual parameters.
So yeah... I think I agree with you in terms of preference. But in reality, I think it's going the other way.
