Cessna CJ4 v Embraer Phenom 300

[Guptar]

I've read some comments lately about the CJ4 and Phenom 300. The Phenom seems to have rave reviews and seems to be selling well. Is it true that the CJ4 is underperforming against the CJ4 or from what it seems reading between the lines, the CJ4 is not meeting its performance targets as promised by Cessna. is there any truth to this?

Would be interested in hearing from anyone who has had experience with both types.
