Ok...let's get something straight.
Ethereum is not Bitcoin.
Ethereum is a blockchain, Bitcoin is an application.
If Bitcoin is like email, Ethereum is like the internet.
Ethereum has more tokens in circulation, so the price difference doesn't matter. Look at market cap (tokens*price).
The "flippening" means Ethereum's market cap goes beyond Bitcoin's market cap.
Market caps (on June 13): Bitcoin = $44.5B, Ethereum =$36.9B
Bitcoin is way slower than Ethereum. It takes way too long to send/receive BTC.
Bitcoin is based on Proof of Work, which is arguably worse than Proof of Stake.
Ethereum is switching over to Proof of Stake very soon.
Bitcoin's founder is....ummm...welll...errrr...we don't know.
Ethereum's founder is a fucking genius.
