Laptop choices

Hi everyone!

I'm thinking of these laptop options... as cheap ones but with amd graphics... what would you say?

Of course that hashcat performance is of interest, but the first two are really low in price, and I cannot figure out HOW MUCH difference in performance there will be, because obviously prefer to spend the little as possible to save for beer, although not the super better ultra megahashes.
