I actually read a thread on this end of the forum where someone did run their car on a Malone tune and a kerma tune. Ultimately, they both dynoed about the same the biggest difference between the two was where the engine power was based on throttle. As I understood it, Malone felt more like an even tune throughout the entire throttle, whereas Kerma was more aggressive, like 10% throttle felt like 30%, 50%felt like 80%, ect.
But as others have said, it'd all a matter of opinion. Only reason I went with Malone was because I didn't want to rent/buy a flashzilla and I found a vendor local who would do the tune for me. Plus the tune works better for me since it's my daily, I don't want to feel like I'm driving a racecar all the time. I rode in a golf that had the same hardware I did, but was tuned by Kerma, and it definitely thew you in the seat more than my car does. Fun, yes, but to me it'd get old.
