Default TSP 231/237 or Speed Inc?

I did a search and read that these use different lobes and was wondering what the plusses and minuses to each was. I am not worried about spring life, and will give up some driveability for more power. I saw a TSP for sale here and was hoping for some answers.
Any proffesional advice?

I think the TSP cam is a lunati cam.

The Speed Inc SI5 231/237 uses Comp lobes that are more agressive.
