This is a mid range, dual SIM handset with better than midrange features such as 87.5% screen/body ratio (5.5 inch display in a body that would previously had a 5 inch display), power efficient Snapdragon SD630, NFC, Nice bright IGZO display, F1.75 camera and very good battery life. 140g and the small size make it easy to use one handed.
As a bonus you get Android Nougat 7.1.1 with Android 8.0 Oreo coming soon) microSD support, Band 5 and Band 28 LTE support!
Downsides are that it has "the notch", Smile UX is not the best launcher, the 630 models have a plastic back, it is shipped with Chinese firmware, you need to install Taiwan firmware for Google Services, which seems straightforward and is explained on the Joybuy page.

For additional info (and if you speak Russian and/or have translate working in Chrome), you can check out the (huge) 4pda forum thread where the Aquos S2 4/64 appears to be very popular.
