Which is better for gaming?

The Crucial P3 Plus. Games now run 50-150GB each, so 256GB leaves room for only a few titles, and its 5,000 MB/s reads load faster than the KingSpec's 3,200 MB/s.

Is the KingSpec fast enough for everyday use?

Yes. At 3,200 MB/s it boots Windows and opens apps quickly. The gap to the P3 Plus shows up mainly in large file transfers and game load times.

The P3 Plus has a stated but low TBW rating; KingSpec does not publish endurance for this drive. For heavy writes, buy a drive with a published, higher TBW rating than either.

Do I need a Gen4 slot for the P3 Plus?

No. It is backward compatible and runs at Gen3 speeds in older systems, so you still get most of its performance on a Gen3 laptop or desktop.

Is the P3 Plus worth the extra cost?

For most shoppers, yes. You get four times the capacity and faster reads for one drive that covers OS, games and files. Choose the KingSpec only if budget is tight and 256GB is enough.

Will either fit my laptop?

Both are M.2 2280 NVMe drives, which fit most modern laptops and desktops. Check that your slot supports NVMe, not just SATA M.2.

KingSpec M.2 2280 256GB NVMe SSD vs Crucial P3 Plus 1TB NVMe SSD

The Crucial P3 Plus 1TB is the better buy for almost everyone: four times the capacity, 5,000 MB/s reads versus 3,200 MB/s, and a mainstream brand with broad compatibility. The KingSpec 256GB only makes sense as a cheap boot drive for an old PC or a light-use build where 256GB is enough.
