Favorite Chains

What are your favorite chains to use and why? How long do they last you? I am about to purchase a new chain for one of our Sonny's conveyors and would love some feedback.

x-458 I used D-88-K for years but switched to X-458 when I replaced my conveyor last time. 458 is easy to work on and requires no tools to seperate the links. Any section can be lengthened or shortened and no cotter pins to worry about.
