chloe7800 This is how I'd rank all the laptops in this thread with only Sims 4 in mind.
Best option overall:

Next-best for Sims 4:

If you're willing to pay for the Dell, you get both the 16 GB RAM and the better performance, so the other 16 GB laptop with the significantly-slower graphics chip isn't worth it. If you're not willing to pay for the Dell AND your priority is Sims 4, then the MSI is the next-best option. The others are no better and at least as expensive so can be crossed off the list.
The new one you found is slower than the Dell and £10 more, so it's also not worth getting if the Dell is an option.
