I have a Samsung Chromebook Plus, and I absolutely despise it as a tablet. Compared to my Nexus 9 (which is still kicking), it's a far inferior device. My primary uses for my tablet are watching video and reading comics. It manages to fail at both of those two things.
1. No system-wide support for red-tint (aka "night mode", Flux, Twilight, etc.)[0]
2. Buggy rotation lock - this works very inconsistently across apps.
3. Heavy (compared to keyboard-less tablets)
4. Buggy soft keyboard (sometimes the soft keyboard just straight-up doesn't work in certain apps, so I have to unfold the device from tablet mode just to use the hardware keyboard to type).
I still use my Nexus 9 over the Chromebook Plus every time I can. When my Nexus 9 dies, I'll probably end up getting a Surface to replace it.
[0] There is finally support for it on a per-user basis, but it took years for them to introduce this. And even now, if you close your tablet and have to unlock it again, you'll be blinded by the unlock screen.
