You are correct about the power ball. Atleast thats how I would go about it. As for what one is stronger, I can only speak from experience and to me they are the same. I figure a power ball would be stronger since there is more surface area. I have not had an issue with either of those on my set up and I drive my car in the winter in -40C... Not that I would advise on that... but they have held up well. I have about 2 years and 40,000km on my set up with little to no maintenance on the heims or power balls.
