I live in NJ and am moving to either northern NJ (Sussex County) in an area which is mountainous and nearly 600' above sea level and is USDA-6a going down to -5F in winter, and rarely -10/15 F; or central NJ (Monmouth County) in an area which is around 250' above sea level and is USDA-zone 6b going down to 10F or rarely 0F in winter over the last 15 years.

In which of the two above conditions would the following fruit & nut shrubs/trees do best - considering cooler night temperatures, colder winter freezes not exceeding -15F, and higher elevation/air drainage of the colder region.

*Sweet Cherry (Prunus avium)
*Sour Cherry (Prunus cerasus)
*Beach Plum (Prunus maritima)
*Japanese & American Persimmon (Diospyros spp.)
*Saskatoon & other Juneberries (Amelanchier spp.)
*Walnut (Juglans spp.)
*Hickory (Carya spp.)
*Peach, Apricot, etc. (Prunus spp.)
*Blackberry, Raspberry, etc. (Rubus spp.)
*Blueberry (Vaccinium spp.)

Thanks,
Steve

Overall, things like microclimate, cost, etc seem like bigger factors unless you absolutely have to have some Japanese persimmons.
