I'm asking, not for myself, but to have ready advice for others.

The Ntrig Surface Pro seems to have the highest number of bug complaints: pen-doesn't-draw, stair casing on diagonal lines, lags, skips, etc., enough to make it virtually unusable for some.

The long-time professional standard, Wacom EMR, is the subject of occasional complaints, but I can't scope out what triggers problems. This is the pen I use, and all of my combinations work. It doesn't malfunction here.

Apple Pencil is acclaimed. As an iPad device, it doesn't really belong in this forum. But the reported excellence cannot be ignored. I tried it at an Apple store, and was very impressed.

Wacom AES is a question. I haven't seen enough testimonials or complaints to make advice I can pass on.
LG makes a very attractive "Gram" tablet convertible using this pen, but there aren't any reports by artists.

On standalone LCD tablets other than Wacom, I have virtually no bug info. ???
