Savage Savant

Hey guys quick question. I've been meaning to read all of the Conan stories and I actually have the first Del Ray Conan book. However I came across the Complete Chronicles of Conan by gollancz and it obviously collects all of the Conan stories & the fragments as well. If I were to buy the last two Del Ray Conan books, it'd only be like four of five dollars more than if I were to buy the gollancz book (that's not including shipping, I'm going by the prices listed on Amazon btw). 

Nonetheless, my question is should I buy the complete chronicles of conan book or should I stick with the del ray books?? I'm a little more inclined to pick up the gollancz book only because it's basically an omnibus of all the conan stories & it seems more convenient than the other way around. My only concern with this book is from the reviews displayed on Amazon, 2 reviewers said the binding wasn't very good & it was kind of simulated leather. 

Anyways, which book(s) do you guys think I should get? Thanks in advance!
