@csillamphoni I would definitely go with the Asus Vivobook, which has a graphics chip that's as good as you'll find for under 500€, at least outside of the occasional clearance sale. It should be able to run all current Sims 4 packs together on at least medium-high or high graphics settings, and you might be able to play on ultra settings depending on which packs you install and your playstyle.
If you can't get this one for some reason, another laptop with an i5-1135G7 would work just as well, as would one with a Ryzen 5 5500U. These are in the same category and should give you roughly the same in-game performance.
