So what would you choose?

Telekinesis. Even with the 50 foot range, it has lots of potential. From its wording, there is no weight limit, and there is no amount limit, so you could wreak havoc in a 50 foot range, and possible throw objects beyond that range. In essence, you should be able to control any object that comes within range of you, so stopping bullets should be possible, and even flight/levitation if you use it on yourself.

i wonder if it would allow you to fly, you probably could considering you're within that range...

a flamethrower and/or explosives would be quite the pain, or if you had to pinpoint/react to whatever you wanted to control (i.e: bullets move to fast for you to notice where they are, so you can't really stop them)
