Those plastic squeeze buckles give me an itch as well--especially any that aren't quite physically large--for any real weigh-bearing tasks. Holding a bag flap closed, okay; holding a camera against two or three gees, no. I also don't like springy straps.
My personal straps are "Frankenstraps" where I took the metal swivel ends from a couple of Domke straps and married them to old-style Tamrac suede leather padded straps before they got the plastic squeeze buckles.
But if I had to get something new today, it would be straight Domke straps with metal swivels. The wide, tough fabric of the Domke straps works well wrapped around the wrist as a hand strap, stays comfortable around the neck, and is secure on the shoulder. The metal swivels are quick to release, but totally secure and swivel so that untangling the camera before putting it on is never necessary.
