Wiko wax vs Acer Liquid E3! HELP!

Hello!
I am going to get a new phone and I need to choose between these 2:
Wiko wax
Acer Liquid E3
(My budget is just of 200€ (aprox)!)

The acer has a better camera, screen,etc. but the battery can't be changed... the wiko wax is 4G, has NVidia Tegra processor and the battery is removable!...
Which one would you recommend me??

Another option would be the xiaomi mi3.. but I think it'd be too complicated since it is pretty urgent and I don't want to pay extra charges (customs/Shipping to europe) (unless you can recommend me safe and quick way to buy it!)

Thanks a lot!
