Performance : Android 6 + 1GB or Android 5 + 2GB?

[rrhirani]

I need to buy tablets for Appsheet. So I read the below article https://help.appsheet.com/en/articles/1097317-supported-mobile-devices-and-browsers but I did not get clear idea.

I have 2 device options.

1. Android 6 or 7 OS + 1 GB RAM (Reference : https://www.gizmochina.com/product/lenovo-tab-10-tb-x103f/)
2. Android 5 + 2GB RAM (Reference : https://www.gsmarena.com/huawei_mediapad_t2_10_0_pro-8303.php)

Which device will give me better performance? My application is very lightweight and I am not doing any operations with images. Having some complex expressions but no image uploading. Downloading images from the background and later using it as offline content.

Any suggestions would be great. Thanks
