When bitcoin and ETH transaction fees are very expensive then the best way is to switch to low cost coins, and in my opinion TRON and MATIC are 2 coins with very low fees, even to send TRON with TRON Link transaction fees is 0 or free.
MATIC wins out over TRON if you are tossing up between the two options.
If you are purely looking to transact value, I've iterated this before but I'll say it again - IOTA/Nano is the clear winner because they allow you to send funds for literally no fee whatsoever.
But if you are looking for DeFi applications, MATIC wins because it has a lot of DeFi protocols within its ecosystem and they had huge incentives to attract liquidity. TRON is archaic in this manner.
