I use a 15-year-old Wacom Intuos 4 (medium size)
I also have an iPad Air 5, but I'm still not very comfortable drawing on it. Although Procreate's realistic brushes are truly amazing, I'm still more comfortable drawing on a PC.
If you want to draw on a mobile device, I recommend iPad (pro or Air)!
For Wacom's products, I personally think it's better to draw on a Cintiq or Intuos on a desktop. In fact, for drawing on PC, I believe the Intuos is already sufficient. It allows me to sit a bit further away from the screen XD.
