@anniieem The second laptop is better in every way that counts: it has a stronger processor, which has a faster integrated graphisc chip; and it has twice the memory, which is necessary because Sims 4 doesn't run very well on systems with 4 GB RAM these days.
If you're interested in seeing more options, please list your budget, and let me know if there are any other details that matter to you. But for under £500, the second laptop might be as good as you'll see. I did find the same model for slightly cheaper on the Dell website though, in case you want to have a look:

Since I'm on that site already, this £500 laptop is a bit better: its processor is newer and somewhat stronger, and its graphics chip is about the same.

The same laptop with twice the storage is £530:

Like i said though, if you're interested in seeing other options, just let me know what you want.
