I really like the simple scandi pouch sheath but would rather have it on my belt than around my neck. A nice compromise would allow both. I only have a kydex point-up neck sheath for reference but I think a point-down system made with a belt loop would give you both carry options.
My favorite sheath right now is the one that came with my BRK&T Kephart. I attached a profile photo of it.
Notice that it has two loops on the back. I use the larger loop on the bottom for my belt and the smaller one on top with a carabiner for my pack. I would think this top loop could also be used for the neck carry option.
The lower belt loop placement makes the knife ride high on my waist. Some don't like this but I really like it. When I'm wearing a coat I want it to ride lower, so I just use a 'biner and connect it to my pants loop.
The third loop on the side is for a firesteel but it can also hold a slim meat thermometer
Also notice the eyelets. They can be used to secure a small pouch or provide other attachment options.
