I'd recommend Autodesk Sketchbook Pro (£8/year) as it's much more of a "Natural" Drawing Product...
As for the smaller tablet … I wouldn't.
Instead I'd recommend something like the XP Pen Deco01, Huion HS610, Wacom One or VEIKK A15
Ideally for 1st Time users of Tablets it's good to go with a Larger Surface Area... and the ones above have reasonably low latency and high pressure sensitivity.
The Wacom is frankly the "Best" in terms of quality; but this said, it's the most basic version that doesn't have shortcut keys; so you will be relying on your Keyboard a lot for those.
