My daughter has the Paradigm.
We really like it. Specifically, she likes the speed bolus button. She also likes the remote, because she can use that in the movies without having to unclip her pump, etc.
I can't speak for the others, but the one drawback so far with the Paradigm is that the batteries have lasted, on average, about a week and a half. We use the recommended Energizer Alkaline, a week and a half seems to be about the working life of the battery.
Hope this helps!
