I have a Hooker and an M6 which has the same handle and very close to the same blade length as the Mojo. I prefer the Res C handle especially with my small hands. If you have really big mitts you might prefer the Mojo. Some people who are used to extremely high end blades like Busse's, Strider's and Chris Reeve have mentioned that the only real issue with Scrapyard is edge retention is not great.
It is only when compared to excellent knives that cost 2 or 3 times as much as a Scrapyard that it is even noticeable. The SR 101 gives up a bit of toughness for more edge retention although the differential heat treat helps in that regard.

I would choose a Scrapper for a hard use big blade where toughness is the most important and a Swamprat for a smaller or predominantly woodworking blade.
