I have two Guardian 3s and a White River M1 Pro, which seems to be the same as the Caper except for a minor handle difference. The huge difference between the two brands is the sheaths.
The White River Kydex sheath is very good. It has excellent retention and also allows a good grip on the handle as you are drawing the knife, even with gloves on. I carry it a lot as a neck knife, but it also works on a belt.
The Bradford sheaths are poor. The belt loop on the leather sheath (I have two) is so tight I can barely get a flat-blade screwdriver under it, much less my belt. The Kydex sheath is usable, but the retention is poor, and I can't get a good grip on the handle to pop the knife out with my thumb. But I did find a cheap leather sheath on Amazon that works with the Guardian 3. Sometimes I use an Armatus sheath, which I think is a must if you are wearing gloves, but it will make my thumb sore if I draw the knife frequently.
For the Guardian 3, I much prefer the "sheepsfoot" blade over the drop point, because the bevel runs into the finger choil on the drop point, making it fairly easy to cut your finger.
The Guardian 3s are flat ground. The White River is hollow ground. That's a matter of personal preference. I find that all three cut very well.
For both brands, the knives themselves are well finished and very sharp out of the box.
