I am not diabetic but I have been enjoying this Kalustyan's PARBOILED BASMATI RICE, which is what it is, and I wish that it was labeled as such (diabetics already know that they should buy parboiled rice).
I cannot compare with other brands of Kalustyan's Basmati rice but this brand is nutty and flavorful and clearly superior to the rice which is available in local grocery stores.
I may keep buying this "Diabetics Basmati Rice" because it is so convenient - pre-soaking is NOT required. You should rinse it of course, but honestly, I usually don't: I just dump one cup of this with two cups of water in my Cuckoo rice cooker, push the button, and wait for it to do its thing...
