Steven,
A gun that does not eject the case without having to turn it upside down or have significant work done to the action to make it eject (I do believe you yourself commented on this issue in your 1999 book, page 85 and 88) I would consider "worst".
Don Allen and I discussed this short coming when I tested some of his initial rifles at a SCI event here in Minnesota where he was demonstrating his rifles. I do not believe he ever fixed the issue.

This discussion I believe is about factory guns and not highly customized rifles.
