If you want to impress your engineerd friends, definitely get the iprobe. It's amazing that it supposedly has a total/electrical probing depth of 5m. I dorked around with one in a busy indoor extravaganza and it was neat, but it would be far more informative to practice with it out on a slope and see if it's helpful.
The other two probes are good heavy patroller type probes. Having a decidedly bad engineering/math brain myself I really like the markings every cm for pit work, which I think the bca has.

Ive got the G3. Can't complain about the quality, but If I had to buy again I would get something smaller than 320. A couple of times, Ive caught myself getting lazy and not pulling it out (tree wells, gullies, creek crossings etc..) just because the extra length is cumbersome.
