I say it depends on use, BM is my favorite brand (no affiliation or endorsements)

That being said, both use the axis lock.

Presidio will be heavier by a good margin.

The Ritter grip and the Presidio both have good grips.

My personal experience with autos, they're nice sometimes when you just want the dang blade open.

The down side to the 5000 is it is an axis auto... no simple button pushing.
