Which tablet is better?

Asus Memo Pad HD &

or

Hisense Sero 7 Pro

I originally bought the Asus Memo HD & but returned it today due to battery issues, and the SD Card not unmounting at all. The batter discharged at night while off 3 different times by more than 30% each time. And it WAS OFF. And have a 150$ gift card for walmart to get a new tablet.

Should I give Asus another try, or go with the Hisense. Note the Asus tablet has history of battery defect and not as good reviews as the Sero 7 Pro. The 8 GB dont matter as I have a memory card, and have less memory on phone, and not used all way up. Its for basic things like read manga, anime, web surf and small games. The reviews showed under 4 star for Asus on Walmart, and 4.1 on Amazon. Hisense has better reviews.
