Generally Dynex Dux is significantly stronger and more abrasion resistant than spectra, in addition it is more stable in UV than spectra is.
The amount of information available is pretty significant, but the expert in applying it to standing rigging is Collegio Marine that first popularized it for use in standing rigging. Last I heard they were suggesting a replacement interval of 8 years in the tropics for uncoated Duc, and even longer with the coated stuff. Just note that it isn't steel, and has its own design issues, specifically creep. Which means that instead of sizing for working load, it is sized for creep, which means you get a rig that is 1/7 the weight, and generally 2-4 times as strong in breaking strength.
