Let me start by saying there is no "wrong" decision with the knives you are looking at. Like Zeppelin albums, listening to III instead of Physical Graffiti is not a "bad" decision, both are great in their own ways. Similar to Fiddlebacks, all the knives you mentioned have differences but all are great in their own ways. Nobody would say it was a wrong decision to grab a Bushfinger over a Hermit or KE Bushie. Much of it comes down to personal preference. I would not get hung up on the hand size, all the knives you are looking at are probably within 1/4" handle length. A Hermit has a more "open" end compared to a Bushie or Bushcrafter but all very close in overall size.
Take a look at this link:

There are some great comparison pictures between the Bushfinger, Kephart, Bushcrafter, Tasker, and Hermit.

Here are great comparisons of the Bushfinger, Hermit, Arete, and KE Bushie.
I personally like the KE Bushie, Hermit, Nessmuk, and Bushfinger within the 4" blade catagory. I would consider the Nessmuk and Bushfinger to be SLIGHTLY better "overall" knives if you throw food prep into the mix (wider/taller blades and the BF is guardless). The KEB and Hermit are certainly not lacking. I have been using a KEB from
Choppaman
the last 18 months for small batoning, food prep, general tasks, etc. and love it. Prior to that, I used a Bushfinger and it was equally great. I recall reading on IG that Cohutta was going to take over production of the KE Bushie. If you are sold on that knife, you might want to reach out to him.
Finally, do not think twice about getting a knife from
Choppaman
! The knife will come to you in the exact same condition it left Andy's shop. He has a huge Fiddleback collection and is amazing to deal with. When he says it is new, it will be new! That Osage Bushfinger from Choppa has tempted me all week! It checks every box. Osage is an awesome material, tapered tang, love the orange pinstripes, and higher grind make it an even better slicer. Consider yourself lucky that it is still there and grab it! Just my option. Good luck and keep is posted.
