I have to disagree. ETH transactions are clearing within 2 minutes or less at a Gas price of 3 Gwei and the BTC Mempool look very empty. BTC transactions are also very cheap. https://ethgasstation.info and https://www.blockchain.com/charts/mempool-state-by-fee-level - there are many other sources to use too.
Strange how info can conflict, but I don't believe the blockchains are that busy at all.
