Murnak would be my second choice.
I've never been able to understand why so many folks like Justis cases. The two rows of rivets are not cool at all, in my estimation, and ruin the looks of the case. I thoroughly dislike rows of rivets. There's gotta be a better, less obtrusive, way of attaching the pieces together. I like the heavy tooling leather.
My other problem with the Justis cases is the pockets. The Justis pockets are very small and are certainly not ergonomic. It's virtually impossible to find stuff that you have in there without taking everything out, you can't see in the pocket at all and the zipper on the side prohibits getting your hand in there. Terrible design. It looks slim & trim but if you are carrying any stuff (like a towel/rag, powder, jump handle, glasses) you'd better have another bag of some sort with you.
I don't care for the On Q use of nails around the top and bottom. I think the nails look cheap and I wonder if they would come loose? Like the rivets I think there has to be a better way. Agree w/John that the inlay work looks great. I do LIKE inlays to match a special cue!
I can't find anything wrong with Murnak's and Whitten's are very classy!
I like JB's the best for my new case because the design window is completely open. I can have my case made without nails or rivets

) ) and have it made with the ergonomics and spiffy looks that I have spent a lot of time thinking about and which pleases my eye and practical needs. Truly a custom case from top to bottom, inside and out. I also like that after I emailed John about my new case he got back to me and although he did not answer real fast his answer showed that he had put some time and mental energy into thinking about my design ideas. He didn't get back quickly because he was letting the mental image of what I wanted get developed in his head and then was spending time developing his ideas of possible improvement over what I suggested. He showed he was truly interested in helping me get the case I really want. Now I'm developing in my mind my original ideas with his suggestions taken into consideration and some new ideas that have come about because of the ideas he had. This is truly a collaborative effort that will get me the case with all the features I've wanted and have it be built by a guy with the knowledge and experience to avoid the pitfalls that some of my amatuer ideas would have caused me to fall into. Working with a pro is fun and this is a cool project.
