Quincunx sampling uses points on the corners, which is kinda like "sampling outside pixel". This will create a better subsample coverage, however, it will also over-soften the image.

Great observation @GuardHei. I was not aware of Quincunx sampling. Do you have a reference to learn more? Where is it used in practice?

@tanick Crytek used this sampling pattern in their temporal antialiasing solution in Crysis 2. Activision re-brought this sampling pattern in their "new" filmic smaa t2x solution in call of duty.
You could find the presentation slides here
