Spandex vs Lyra: Which one is the strongest contestant

[Torchwatch]

Spandex is a generic term referring to stretch fabrics (2 or 4 way) in which Elastane is used as the stretch agent.
Lycra is Dupont's registered product and is a 4 way stretch spandex.

4 way stretch Spandex is superior to 2 way stretch Spandex so Lycra is superior to 2 way stretch Spandex but may or may not be superior to other manufacturers 4 way stretch Spandexes.

This question is like asking if a Hoover is better than a vacuum cleaner. Do you have Hoovers in the USA ?
