I would agree with your friend that it has more low end, but overall (or peak HP) power is REALLY close between the two. I have driven both extensively and MUCH prefer the VA over the EZ, but cannot decide which has more power overall.
You could not trade me two more EZ's for the VA I have now. started with the VA, went to an EZ, and did not look back when I got another VA.
No-one get me wrong, the EZ does EXACTLY what it is advertised to do, it just did not do what I wanted and the VA did.
