Smoke,
The Lowa Camino's and the Salomon Quest 4D are a lot more boot than the Renegade. Stiffer, a lot more torsional stability and a bit heavier, both great boots but really a different category than the Renegade.
I have a pair of 4D's coming for myself and might add the Camino one day as well.
At the store I work at we carry all three of the above as well as Lowa Hunter Extreme and most of the Kenetrek's, so it nice to give the customer the option of trying on the various boots.
It all comes down to what is going to work best for you and how well they fit your foot.
