Most reliable material for Low Slope Roofing

Hi, I have a low slope roof and need 30 year + and reliable performance material.    Some roofers recommend Duralast PVC 60mil , some said Firestone EPDM 60mil. What is your opinion? Which product made by which company you think is better? Or do you have other suggestions? 

Thank you! 

Though my vote in the favour of PVC but Your climate also matters. It is also good to discuss with your roofer before finalizing your decision.
