Given your stated reasons, David, I'd go for the half case. I also have both Gariz and MegaGear cases for various cameras. It's really a subjective call. If you just want a utilitarian case that'll do the job, go with the MegaGear version. If you want to impress others, go with the Gariz, which in all fairness does look and smell better.
Meike grip is here, pretty nice, adds plenty of grip. Feel nice and secure while holding the camera and bringing it up to my eye.
And I think I'm going to return it. Why?
Holding it with my wrist straight and EVF to my eye it's fine. But waist level and off angle stuff it puts my wrist at an uncomfortable angle. If I had or planned on getting longer lenses I might keep it for them.
