Which latitude - recommendations

So following on from some excellent advice, I'm now trawling the internet to find a replacement.

Can anyone advise please which is the best out of these models?

LATITUDE 7290 ULTRA BOOK CORE I3 8th GEN 8130U 8GB 250GB SSD HD

Latitude 5480 i5 6200U 2.30 GHz 8GB RAM 240GB SSD

Latitude E7270 Intel Core i5 6th Gen 8GB RAM 256GB SSD

Latitude E7470 Core i5, 8GB RAM, 512GB SDD

E7470 Core i7, 16GB RAM, 256GB SDD

They're all coming up in around a similar price range for a renewed one (which is about all I can afford at the moment sadly)

Thank you in advance
