Thinking about buying either a Samsung S6 tablet or a Lenovo M11 tablet to use as a graphics tablet

Title. I've been needing pressure sensitivity for some 3D art projects and found out I could use my phone (S21 ultra w/ s-pen) as an impromptu graphics tablet by using SuperDisplay. I thought this was going to be a bad experience (high latency, etc), but I was extremely surprised how good it was, with the only issue being that it was difficult drawing on such a small display.

This had led me to want to upgrade to a tablet with a stylus. The most obvious choice was a Samsung tablet (S6 or later) since pretty much all models S6 and on support S-pen, but even secondhand ones seemed a bit on the expensive side.

I found out about the Lenovo M11 tablet which has a stylus with a bunch of nice features (tilt detection, pressure sensitivity, etc) for around $100 cheaper, but I'm not sure if it's stylus would be compatible with SuperDisplay (it should, but I cannot find any actual evidence that it does).

What's the best option for me? I don't mind spending a bit of extra money on something that I know will work, but I also don't mind spending less on a (somewhat) inferior tablet if it will give me basically the same experience.

Or is this just a stupid idea in general and I should buy a dedicated graphics display? (X-Pen and Huion both sell graphics tablets with screens for around the same price as an S6)
