I like mine so well that I bought an extra one just in case I loose it. I prefer the old style clip.
The 0550 is a big, heavy, thick blade, knife, if that's what you're after then it's a great choice. Others to look at would be a Benchmade 810 Contego, 950? Rift, Adamas, etc. Spyderco Para 2 is about the same blade length but much lighter and more compact. Strider SGN is kind of the best of both worlds being a thicker blade than the 0550 and lighter/more compact... ...more money though.
The short answer is that you can't go too far wrong with an 0550.
