That's what I thought as well, but my experience contradicts that. Wacom is expensive, but it still leads in terms of sensitivity and accuracy. The pressure levels and other specs don't tell the full story.
On both my iPad Pro (2017) and an open-box Huion H610 Pro (pretty old) I saw stairstepping behavior when drawing a straight line with a ruler on a diagonal. It wasn't very pronounced on the iPad, but it was still there. If you draw the stroke quickly, the smoothing kicks in and straightens it. I'm pretty sure this is a normal side effect of the tech used to identify the grid coordinate of the stylus. But the wobbling was notably bad on the Huion. https://imgur.com/a/iPNZzrY
When I got a Wacom Intuos Pro PTH660 (Amazon renewed), the same test without smoothing showed a perfectly straight line, even when drawing quite slowly.
I don't know why the Wacom is better. Maybe it's got a higher resolution grid for detecting the pen location. Or maybe it's just got better tuned drivers. It's also much easier to freehand accurate lines and ellipses on the Wacom.
You generally can't trust the reviews of Wacom alternatives on YouTube. As reported by Aaron Rutten, most of the companies are not looking for fair and unbiased reviews: https://www.youtube.com/watch?v=Twy5Wo8m284&t=337
