Did you even look at the graphic I linked to? If so, there’s no need to “go look” at anything, since that graphic very clearly shows there’s not a major difference.
If you're doing primarily vertical tasks (coding, web pages, etc.), the taller aspect ratio can be really helpful.
That said, I've mostly made my peace with 16:9. Write shorter functions (that's good anyway) and throw bars over to the side instead of top and bottom.
And specifically for an xps 13 device, where they trim excess bezels, etc., the keyboard width becomes the limiting factor.
Here's a better image though, rather than a really weird bunch of lines for camera sensors: https://wolfcrow.com/wp-content/uploads/2013/01/43169aspectc...
It's about 20% more vertical space, as you can see (and you have to put together the top and bottom, which is a lot more impressive).
