@beesmart3 Just to be clear, among the components in a given system, the single most important one in determining how well a computer runs Sims 4 is the graphics card. (This is true for most games.) Extra hard drive space is nice to have, but if you're only going to use this laptop for Sims 4 and maybe some small apps (browsers, Spotify, etc.), 256 GB is more than enough.
In your price range, there are two good graphics cards that are commonly available and would run Sims 4 on ultra graphics settings. The cheaper and slower Nvidia 1050 would only barely handle ultra settings, and that might not be true as future packs are released. The newer and faster Nvidia 1650 would handle ultra settings with some room to spare, meaning you'd have an extra margin to account for some demanding expansion that hasn't been released yet. While we don't know what the game will look like by the time it's out of development, the 1650 is right on the border of what we'd guess would be necessary for ultra settings.
There are plenty of options for each graphics card, depending on how much you want to spend for extra features. This Acer and this HP both have exactly the same core components, including a 1050. They're both $630, or you could get the same HP (except with a smaller screen) for $650 at Target, plus a $50 gift card.

Laptops with an Nvidia 1650 start at $700. This MSI has the same specs as the Acer and HP, other than the faster GPU.

An HP with the same specs, except a 512 GB solid state drive, costs $750 at Target, again with a $50 gift card included.

Other than those, the laptops I saw with a 1650 and more storage were $800 and up. This MSI is the same as the other MSI except for storage:

This Asus has a slightly stronger processor than the others mentioned, although it wouldn't matter to Sims 4; and a combination 256 GB SSD/1 TB HDD:

This Asus has a much stronger processor than the others and a 512 GB SSD:

For comparison, since you were considering a Dell, these are the two best options with a 1050 and a 1650 in the Dell store:

So you'd pay significantly more for the same hardware, even before the extended protection plan. Dell does make good laptops, even good gaming laptops, but so do Asus and MSI, and for a lower price. HP is fine too, pretty much the same as other brands in its price range. There's a chance you'd get a lemon with any brand, even the very high-end ones, but that's what warranties are for.
