depends on which kind of teleportation, interdimensional or matter transporting in the same reality. Nightcrawlers and azazel teleportaiton is all interdimensional, so more advanced(at least azazels teleportaiton is more advanced than nightcrawlers, because he can teleport anywhere even if he never been there. Or like dofp apocalypse, teleportation bubble forms and it teleports you to another location, cons is it takes a long time to form it, but benefits from teleport multiple people without any straining.
