Which is better for gaming?

Neither is a real gaming PC; both use integrated Intel graphics. The Acer is the better base because its PCIe x16 slot and 300 W PSU let you add a graphics card, but you would also want more RAM.

Is the Dell worth $200 more?

Only if you value the smaller, quieter case and Dell onsite service. On raw performance the Acer's 10-core i5 beats the Dell's 4-core i3 at a lower price.

Which has the better processor?

The Acer. Its Core i5-14400 has 10 cores and boosts to 4.7 GHz; the Dell's Core i3-14100 has 4 cores at a 3.5 GHz base clock.

Can I upgrade the RAM in both?

The Acer has two DDR5 slots and ships with 8 GB, so adding a second stick is straightforward. Dell lists 8 GB DDR5 but does not detail slot count in the given specs.

Which is quieter and smaller?

The Dell. Reviewers consistently call the Slim Desktop compact and quiet; the Acer is a 17.19 lb tower.

Do either include a monitor?

No. The Acer ships with a wired keyboard and mouse only, and the Dell listing is the desktop alone.
