Chuwi Hi10 or Pipo W1S

I need suggestion for these 2 tablets:

1.Chuwi Hi10

2.Pipo W1S

http://www.gearbest.com/tablet-pcs/pp_253958.html

In my country those 2 has around $100 difference( Pipo has include the docking keyboard but Chuwi not include it) and only with 1 month distributor warranty

some question about those two is:

1. Is CHuwi Hi10 still have some random problematic problem that occur around screen, charger and rom 32/64 bit difference?
2. Which is better for long usage(around 2-3 years maybe)  between Chuwi and Pipo?
3. If you are me, which tablet you choose : the Hi10 or W1s?
