ASE Performance chip or Hyper-tech

[2000 GMC]

I've read on this forum about the Hypertech, but has anyone used an ASE Performance chip?  If so what are the advantages or disadvantages of each?  Thanks

I have an HPP, I like it because you can constantly play with it if you want. Change shift points, rev limiter, recalibrate the speedo if you get different size tires or changed rear end gears. You can tune for either 87 or 92 gas and use a lower t-stat if you want. I would think a chip is limited to the one time prgramming, no versatility.
