Depends on the game. I still play a game that's almost 20 years old (the original Descent), which has a small but active multiplayer community [0]. I regularly play against players in my own house as well as players from as far away as Brazil, Qatar, and Australia -- so I have to deal with various connection consistency issues. Given the game physics, I would much rather have out-of-order packets (resulting in an opposing ship briefly flashing in a wrong location and firing a shot from there) than having a delay on in-order packets (resulting in an opposing ship completely freezing, and then completing several seconds of movement and several seconds of shots in a fraction of a second). There are other games that behave differently, where TCP would be preferable. [0] descentrangers.com for anarchy, cooperative, and team games; descentchampions.org for competitive 1v1s.
