Oh boy... wow this is an interesting question with probably a loaded answer to come... I'm going to keep it simple, lol.
I had The One and I have the Paradigm... Notice the words "had" and "have".
I actually was throwing both balls in my arsenal for a while and here's what I can tell you from how they worked for ME. The Paradigm was much more versatile and most importantly to me... it was more PREDICTABLE.
The One tended to skid on oil more than the Paradigm, and contrary to what people say about these balls being similar, they seemed to be very different looks to me. The One gave me more of a "snap" and the Paradigm gave a strong "arc" with a strong backend. I got into more trouble with The One (splits, buckets, you name it!), so needless to say, I sold it.
Now, this is my opinion and I may play an entirely different game than you, so take it for what it's worth. The One is a tremendous ball... I just prefer the Paradigm for my game. Happy shopping!
