Traffic info is excellent. You can see if you're going to be ramed up the a*se and from those places that you can't see. For example a biz jet was descending from my RH side above the wing of a 182, and I could see them coming on the traffic display but not visually . No doubt they had TCAS anyway, but assuming they hadn't and hadn't seen us.........
It is ok in the circuit, makes it easier to see where numbers 1,2 and 3 are, and it doesn't distract....
Cheers
