LRC and Polygon opinions from real ETH users

Hello ETH users !

From lurking here I am under the impression that gas fees are one of the big weakness of ETH for the moment. If I understood correctly, other token as LRC and MATIC allow to reduce those fees.

From a user point of view, how practical are those both solutions? I am having trouble understanding if both token do the same thing. If yes, which one is better?

Thanks for your help !
