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 by a long shot, though I would be afraid it would make me fat and unhealthy (never walking just teleporting everywhere).
If you are saying I can hold another person and teleport us both? Abso-damn-lutely teleportation, can you imagine the savings on travel?
Thinking too small.
Contract out to nasa or highest bidder and transport goods and people to ISS. Transport goods and people to mars. Get spacesuits and transport asteroids to the highest bidder. Become richest person on earth.
This is actually partly the plot of one of the later Jumper novels by Steven Gould.
Plot twist: The conspiracies are true and NASA drugs you and abducts to you experiment on you and learns to milk that sweet teleportatium out your ears while tied up in an underground warehouse somewhere in Area 51.
Oh great now it’s a horror story.
