Primecoin mining vs protoshares

Wonder what’s more profitable now? Is there like a hardware comparison chart?

I have not seen a comparison chart, and I dont think there is a general way to be sure.

Protoshares are more expensive, but they have more miners.

Personally, what I would do is spend a day mining primecoins, and another day mining protoshares, and then see which one would get you more money in that amount of time.

EDIT: Protoshares hardware comparison:

Why not mine both and see what you get more of in a 24 hour period in USD$$?
here is some super simple software to do just that.
