According to me , among all the budget fablets redmi note 4g is the best. This is because it has a high price to performance ratio. Its touch is brilliant ( even though it does not have gorrila glass) , its cellular call quality is simply amazing, sound output is good. It still runs on android kitkat and has a custom MIUI 5 out of the box. The cons of the device which I found were that it has some minor heating issues i.e after some time usage the phone got heated up and lagged quite a bit, and the second con is that there is still no announcement from xiaomi about upgrade to lollipop version. Overall its a very good device.
