just a suggestion here - consider some barley and oat groats too. the different grains cook and boil with slightly different flavors. The shelf life is roughly the same.
with wheat,
the protein content of hard red is a bit better than white wheat but not so's you'de notice much. Most of the whichness of the whyness arguments i hear about wheat come from bakers using flour.
I use sprouted barley and wheat (just field run, not fancy cleaned stuff). Its great for fodder in the winter for chickens and sheep - as a treat on cold days. They treat it like cotton candy. With a bit of garlic oil in a salad or stir fried, i find it tasty too. sprouting wheat makes it taste better and changes the nutrition palette.
I'll second JM's suggestion - try a bit and get what you like.
