At least one...
I know folks that have both. There are pro's and con's on both, but they are subtle. Watch them both fly and talk to the pilots and get their impressions. The V4 is load sharing, the Adverrun is not. The Adverrun is quieter, but IMO the V4 is a bit more refined in power application. The Adverrun's motor hangs low, gets better cooling. My V4 motor, which is inline with the spinner, barely gets warm.
