Apple iPad Mini 3 vs 4 for price diff of US$20

I'm choosing between a used iPad Mini 3 vs Mini 4:

The difference in price between both from a refurbished dealer is US$20
(for 16GB, both with Wifi : guess they don't have cellular built in).

Is it worth the US$20 to go for Mini 4?  I heard Mini 4 can go for a later
versions of IOS (security patches & bugs), is this crucial?

I think the link above made a mistake indicating the Facetime camera (front-facing cam) at 2Mpixel
for Mini 3 : think both Mini 3 & 4's  Facetime cams are 1.2Mpixels,  help confirm this

The iPad Mini 3 has been removed although there are surely some in the pipeline.

For $20 , I would get the newer one. I read the reviews and it is a good machine.

My grandchildren have the Mini 3 and since they already have that model, it will be fine for them. But buying again now, we would get the Mini 4.

I have doubts on the link above saying it's 2Mpixel for Mini 3.

One last question: is it labelled anywhere or I can view from IOS'  Settings
option the hardware model?  Just want a way to verify when the item arrives

Facetime both models is the same resolution so far as I know.

Go to Settings, General, About in IOS and it tells you all about the phone

Thanks and good luck with your new Mini.
The main difference is that  the iPad4 Mini rear camera is 8mp instead of 5mp and it has a faster cpu.
The ipad4 mini is also thinner and lighter than the ipad3 mini.  Everything else is the same.  The front facing camera on both are 1.2 mp.
