You could turn invisibility on and off as you like and there would be no time limit. Your clothes would turn invisible too, and you could decide whether the items you are holding would be visible or not.
There would be no limits on how many times or where you could teleport. The items you hold while teleporting would be teleported too. You would also have the ability to know if the place would be safe to teleport to, so you wouldn't teleport and get impaled by an icicle or teleport inside a wall and get your insides filled with concrete or something.
Personally, I don't know which one would I pick. Invisibility would be awesome for pranks and stuff, but teleportation probably would be more useful for everyday life.
I'm struggling to think of any situation in which invisibility would benefit me personally. Teleportation would save me over an hour a day of driving to/from work alone, plus hours at work itself, fuel & vehicle maintenance costs just about disappear, world travel becomes something possible to do any time of any day on a whim, you could do anything.
