I own a GW690ii, love it, and am about to supplement it with a newer GW690iii. The differences are very minor, with slightly better odds of getting a low-mileage camera in the later iii version, though if you encounter a lightly used ii version, it will probably be a hundred dollars or so less. I lucked out on a ii which had an immaculate main lens and clean inside, but a number of cosmetic scuffs to the body which brought the price way down. Sometimes it's nice to have a functional "beater" camera that you don't have to get paranoid about if it gets another minor scuff or scrape on the body, especially since I take these things into mountain storm conditions and so forth. The lack of a true T setting is a minor annoyance; but so far, it hasn't lost me any shots. Like all wide-angle lenses, the biggest concern is flare when aimed toward the sun. The retracting hoods on both models cause a tiny bit of vignetting to the lower corner of the rangefinder view with full 6x9 when the hood is extended. Again, a minor nuisance I quickly got accustomed to. I haven't had any problems loading film.
