whats better edge evolution or hp tunners?

I have the Edge Evolution CTS and like it. Haven't had it all that long but even in economy mode there is a difference in power and how the tranny shifts. Haven't filled up with 91 Octane to try the extreme mode yet.

hp tuners if you know what you are doing or have someone with the knowledge to program for you

HP Tuners with somebody who knows what they're doing.
