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.
Teleportation is the queen of all powers. Invisibility can be basically mimicked with quick teleportation work if needed.
Although my legs would probably atrophy from lack of use, lol. Why walk to the kitchen when I could blink there and get a sandwich and blink back in no time at all?
Interesting view point. I would have to consider whether time still passes for the user of the power? If you freeze time for everyone else, do you still age? And if so, I would still take teleportation over that as travel would be instant vs "appearing" instant to outside perspectives.

But still you can't win against the invisible man who steals your sandwich after you brought it back.
Then you have to go fetch another one and he grabs it again. :-)
