I would suggest that you review the manufacturer's specifications for the products you're interested in installing. Nobody will know the products better or have tested them in more conditions that the manufacturer. They'll be able to tell you the environmental constraints, like minimum and maximum temperatures and water resistance.
If you can't find these items listed on the spec sheets, use the &quot;contact us&quot; link that's bound to be somewhere on their web-site to send them a question to ask specifically.
As to which one is better - that's a personal opinion, and we can't answer that for you, especially since you haven't defined what criteria you're interested in measuring to determining &quot;better&quot;.
