Gravity gun, the portal gun would honestly end up killing most of us, bad momentum and you go splat. The fact that you have to travel one place, open a portal and then open a portal in a another place is ok if you're going to travel back and forth repeatedly between those two places. It clearly doesn't work like how some people are saying, you have to physically see and be able to shoot the spot you intend to go to, you can't just decide hey I want to open a portal in a bank vault. Also the fact is that even if you wanted to use a portal between work and home to save you the time, the fact remains that there is a gaping hole left at your work and your home that anyone can walk through. There has been nothing in the game to indicate that the portal gun can willingly close a portal, the only means is by opening a new one. So unless you want to grant people free access to your home, and the fact that your employer probably wouldn't want to grant you free access to work at any hour of the night...it probably wouldn't work out. And even if you could willingly close a portal you'd have to drive back to work/home to open a new portal.
Whereas the gravity gun would be a somewhat useful tool, hell you could open up a 1 man moving company and make a ton of money.
