I usually just buy the standard ink but I was printing a lot of photos and my standard ink was gone in no time. This has so far lasted twice as long for the same number of prints and still have 1/3 of cartridge left. I'm thinking it's a better value overall. I plan to buy the XL from now on for both black and tri-colour cartridges. My personal opinion is that ink is far too expensive, but at least you are getting more for your money with the XL.
