Not sure if I should be putting in the effort going by your tone, but just for my own conscience:
We can debate taste all day, but that's not going anywhere. I prefer BotW's more elegant, less "hyped" art style, but can see why people like X3. I'm not trying to take anything away from their enjoyment.
We can also debate technicalities all day. X3 has per object motion blur. BotW has dynamic world shadows. X3 has more characters on screen. BotW has a single seamless open world. Both have procedural cloud cover. I didn't intend to start a stick measuring contest. Different stuff has different priorities for people.
Personally I haven't seen a more impressive game on Switch since BotW in 2017, and that's kind of a shame because I'd hoped BotW to be a starting point and not a continuous shining example. Xeno's low resolution has more of that "impossible port" feeling than something that feels like it suits the Switch.
EDIT: added two BotW screenshots of my own because the two you provided are obviously selected to prove your point.
