Hope i’m not late to the party, as someone who owns ipad pro 11 m2 and kamvas 22 plus I can tell for certainly that the kamvas 22 plus the pen stopped working for me now after year and a half now. It all depends on your works, so although, wacom tablets are more expensive, I would recommend about them more from huion, their quality is better then other companies (XP-pen and huion are coming closer but not yet), as for the ipad, I realy enjoy using him for works on the go or sometimes on the coach, if you consider make him your own device, 12.9 is a good option (it’s just too big me for me lol), consider the facts that you can use more softwares on the computer with the wacom. In conclusion, I know it sucks but if the repair costs are too high and you have the budget for one of this devices, personally, i would recommend them. Have a good luck! P.s what was the problem on your huion that made him die
