I have JK Kephart & JK Kit, Breeden Kat x2, Pathfinder, Peacemaker and 2 custom ones...
The orange one above was the original kat - 3.25", and the osage orange one was a modified one by putting the Kat knife with the PSK handle. Bearthedog designed similar to this but with a wider blade.
Here is peacemaker and JK kephart , modified cat together
Breeden pathfinder - currently this one is my favorite
Another comparison shot - Third one down is a model I designed and build by Breeden called the BigPaw - it's extra long handle was developed so that I can use it comfortably with gloves. It works great for that purpose.
Some of the smaller ones - here is my modified kat next to the RC3. Third one below that is a custom kephart by CKE2
This was my newest one from Breeden - it has (difficult to see) a scandi grind and bocote handle. This new sheath style as his has a cross configuration so that the knife can be carried horizontal or vertical. I really prefer his new sheath style.
btw - John (JK) offers his knives in either kydex or leather. I've dealt with John and Bryan personally. They are both great guys to deal with. They both make excellent knives. As somebody else said, the one you decide to go for is really based on aesthetics. If you contact John or Bryan, they will pretty much modify your knife to your exact specifications. You can choose you wood, handle width, handle length, handle style etc. They also both do 1095 and O1. Can't go wrong with either of them.
