I had a Hiker and bought a Bulldog and a Titan to see the difference for myself. Hiker is small and light. Works great but I've broken a few buckles on them over the years. Titanium and Bulldog are larger, thicker and have a stronger buckle. I prefer the titanium buckle but both are good. both are snap-proof and non-slip, and best of all, both are metal-free, so great for travel.
