Hi Nab,
Couple of home owners I know have the fake/plastic stuff, oh Shityeah it gets hot.
Sure, you don't have to re oil, worry about water damage, but try and stand on it in full sun, you might as well walk through a fire/coal pit.
Put down right, coated with the right product, looked after and a timber Hardwood will last for years.
A tip, timber joist I run down each one a length of Snake Skin, poly flashing, nailed to the side of the joist, to protect it from water being trapped under the decking material.
I've pulled up deck that was only 5 years old and the rot between the decking & joist was enough to replace the joists.
Hope this helps.
