Let me laugh at what you said. Bitcoin is just lucky to be the first on the line thats what it makes its price dominating and aside from that a lot of people are still confused using it. Ethereum transactions can be confirmed for only 20 seconds while BTC takes 10 minutes, so which is the best for you? lol
You do realize that speed isn't the only benchmark right? You're ignoring decentralization and actual security. If speed is the only thing you're going to look at anyway, then go use PayPal. Also taking note that Ether isn't even actually made for payments so ETH and BTC aren't even direct competitors.
