A smartphone is the ultimate, single-user personal computer. Choosing a device is too intimate for me to use any sort of tabular comparison tool. The device needs to be right for me qualitatively also.
I strongly recommend picking a handful of devices and getting a variety of opinions from reviewers. Then, weigh those opinions against what features are most important to you.
If this is your main computer which most likely it is for most people, it's worthwhile to spend some time on selection.
I have a monitor that's almost like this and it's surprisingly nice. It feels like a two-monitor setup. Two actual monitors would probably have been cheaper, but I got mine from work, so it wasn't a factor.
The real advantage of having two actual monitors is being able to flip one vertically for reading code.
Good news; a true necessity if eSIM is to be consumer friendly.
