How much worse is a 635 than a 640?

Is a 635 slower than a 640? Is the camera worse? Is there less internal memory? What are the differences?

Here's the differences compared to the 640...

The 635...

...has half the RAM, which meant Facebook and Messenger refused to run in my case on W10M, multitasking is less smooth and whatnot. But it works for the basics.

HOWEVER, there are some 635's that have 1 GB of RAM, matching the 640.

...is not supported currently so you won't be getting Windows 10 Mobile easily, although some 635's have indeed been getting it with little effort oddly enough.

...has an inferior, lower-resolution 5 MP camera with no LED flash. (the 640 has a flash and an 8 MP shooter)

...is smaller than the 640.

...does not have a proximity sensor.

...does not have double-tap to wake or Glance.

...has a smaller and lower-resolution display.

...has a smaller battery.

Although the 635 and 640 share the same Snapdragon 400 processor and 8 GB of storage + microSD.

The 640 is the better all-around phone but I your needs are very basic and the 635 is significantly cheaper then the 635 may make sense.
