Refurbished Dell Latitude 5510 vs 5511? Are either of these good laptops?

Needed help recommending a laptop for my dad. He's going to be using it strictly at home for business use so someone suggested the Dell Latitude 5000 series

I found these 2 refurbished models and was wondering if either are worth considering:
