I was not sure which game I should post this thread in but this is probably the best choice due to the nature of the question. In my opinion Blitzball is without question (at least in my eyes) the best optional game/sidequest. I do like Triple Triad from FF8 and despise Tetra Mater from FF9. I will admit that at times Blitzball can get mildly tedious but it is nowhere near as annoying as Triple Triad (however I love playing Triple Triad) when certain rules are imposed on you and Tetra Master is just a bag of shite. Anyone disagree or have any views on it let me know.
