If you are not happy with the high fees of btc, just use litecoin. Don’t waste your time with bch which is a failed project. Litecoin has been dominating the on-chain purchases on bitpay for months now.
Or just use Monero and enjoy top anonymity levels and the lowest fees.
But don't forget Monero theoretically have lower TPS. While Monero have 2 minute block time, Monero TX is bigger and has smaller block size than Bitcoin. Looking at
https://moneroj.net/blocksize/, current average Monero block size is only about 342KB.
