Bitcoin cash is the only cryptocurrency I have regularly used in the past 3-4 years. Almost all the crypto payment options support bch seamlessly (because they aim to integrate bitcoin which results in no-effort integration of bitcoin cash).

I just can never get myself to pay the tx fees of bitcoin or ether. I recently discover that USDT exists on bch (but BitPay doesn't accept bch usdt) so I keep USDT on BCH and do JIT swaps to BCH and make almost zero fee payments.

Just to be clear, BCH will never dethrone BTC, but BCH is becoming a defacto layer 2 solution for Bitcoin. Now there are tokens and NFT tokens on BCH too.
