Also, those are both Celerons. Don’t get a Celeron. “Jumper”? WTF brand is that?
Get a 2 year old used computer off backmarket or something. It’ll be way better:

These are off-brand machines with extremely low end cpus. I would expect zero warranty support and extreme cost cutting measures everywhere. I would suggest taking a look at some of the better known brands and what they offer in this price point. Lenovo has the IdeaPad 1 line with several machines around this price point, I’m sure some of the others do as well.
But to answer your question: the 16" has a newer and much faster CPU, more memory, and a better display ratio (this one is somewhat preference but I really like 16:10 on laptops).
