If it's just a small shed then either will do. If you're concerned then there is no reason why you could not double up. Or use a thinner layer as a base, and then put the one you have shown on top.

The second item is the one to use.

If you read the description of the first item, you will see that is specifically for '2 layer traditional roll and pour roofing'.

I would always recommend EPDM rubber roofing, it just seems like the sensible choice nowadays as you know it's going to be extremely durable. I recently got my roof re-done, and found a useful site to get an estimate and all the materials from waterproofsystems.co.uk
