I've not used the 8022, but the college I studied at had an 822 which could well be essentially the same microphone. I mostly used it for recording atmos and generally remember it a a mic which was easy to use with a good sound.
This sound was recorded with the 822:

Handling noise was fine, but if you want to use it out and about I'd recommend getting a pistol grip and windjammer of some kind.
I've not used the NT4, but it looks more like a mic designed for the studio. It certainly has quite a wide body which may make it a more difficult to mount etc. Weight of NT4 is 480g, 8022 is 247g. There is also no protection for the capsules. This is all speculation though, perhaps some NT4 owners will chip in here?
Hope this helps,
Mark
