The only real difference between the Alpha Systems # AL74UV and the LaSalle Bristol # 3441700534142711440 is that the Alpha Systems is made of TPO which is a bit less flexible than Elvaloy-based PVC that # 3441700534142711440 uses; PVC is going to be a bit more durable and puncture resistant than TPO.

Also, the two types of membranes can be used together so you'd be able to use the two at the same time if you wanted.
