Here's my take - I did this sort of matrix when I looked at laptops
From my analysis, the Go represents the worst value, because you get a dual core pentium cpu and 128GB of storage and have to buy the keyboard and stylus, yet when you factor in the keyboard and stylus, its not that much less money. The price certainly can go down without either but I think overall for the type of work, I'm looking the keyboard is a must have.
The X1 and SP represent a class machine that may be over kill (for me) and they are both a bit pricey. That leaves the switch 5, slightly smaller then the SP/X1 but a bit larger then the Go and it running an i5 as opposed to a pentium, so performance will be a bit better and the storage is a healthier 256GB
The switch's bezels look a tad thinner on the top and bottom, but its hard to see how the sides compare. The images I've seen on the internet are almost always the Go with dark mode, or back screen, presumably to hide the bezels. I understand the bezel size is helpful to hold, and even on the iPad I was a bit critical of losing bezel space for that very reason. I believe there can be a happy balance, though I don't think the Go has achieved that.
I really like the mil-spec'd X1 tablet - it looks incredibly durable and will last a long time, but its way more money that I'm willing to spend. The switch looks like a nice balance of size, performance and price, especially if I keep an eye out for deals. I've seen prices as low as 699, though that sale must have ended since amazon is showing 730 as of today.
