Im in Zone 5, and I've never heard of those.
Where are you finding these?
Local nursery?

Some are local, some are from other parts of the country (canada). Here are the breeders for them if that helps:

Hazen - UND http://library.ndsu.edu/tools/dspace/load/?file=/repository/bitstream/handle/10365/4353/farm_37_5_1.pdf?sequence=1

Goodland - Modern research station Morden, Manitoba

Prarie Magic - "A seedling of the cross �Goodland� x �Mantet� selected by the late Mr.
Wilfred Drysdale of Neepawa, MB. Introduced by Jeffries Nurseries Ltd." http://www.jeffriesnurseries.com/prairiemagic.pdf

Beacon - Minnesota

Parkland - Alberta

Since youre in zone 5, there would be no real reason you would need to know any of these, since they are all (except beacon), bred to grow in the Canadian Praries, or Minnesota.

For me, its just what is available here. Trust me, id much rather have a spartan or gala tree. I do however have access to "honeycrisp" (next year).

Goodland and Parkland I have, I would drop these.
The top eating apple here is Norkent, then for cooking and eaing the Prarie Magic, September Ruby is good too. Best early eating is Norland but doesn't keep long, the other two you mention I don't know.

Goodland/Parkland just not great tasting? I would personally eat them fresh, or juice but I know people who would bake with them...

They did have Norkent as well as Norland. They had a few others like red delicious sports (dont like the taste too much myself), green transparent, honeycrisp (again, next year) and Honeygold (already have). Its just a bit late in the year, and I can get a decent tree for cheap.

Goodland/Parkland are tart, good for cooking.
