Trex vx. Azek for decking

[Brandon Ingegneri]

It has been a few years since I have built a deck, and I recently bought a summer rental/beach house.  In that time, I know that Trex and Azek have come a long way.  I was curious the pros and cons of each to help make a decision of what decking material I want to use.  In the past, Trex got extremely hot, and Azek scratched very easily.  I am looking to install the most durable and longest lasting product. 

I am limiting to these two materials first because I am not interested installing a PT deck, and secondly, because the supply house that I regularly utilize mainly carries these two brands.  

All input welcome.  Thanks in advance!
