I agree Ipad is better for long term use and productivity.
But for less than 15k you are getting some great high specs Android tablets too with amazing 2k display.
So both choice should serve you well.
If I was in your case and I needed something for mostly content watching. I would go for andriod tablet with good 2k+ display and big battery and fast charging.
If I needed something to study and do some productivity work. I would go for Ipad.
