The number of confirmations needed to feel like a tx is secure and the throughput of the network are not related. Regardless of that, you're still wrong about security and confirmations, using your own source.

ETH ave. block time: 10s. Time to get to Coinbase confirmations (35): ~350s

BTC ave. block time: 10m. Time to get to Coinbase confirmations (3): ~1800s

So I can make 5-6 transactions that coinbase thinks is "secure enough" on Ethereum in the time it would take me to make one transaction with Bitcoin.

Add to that the fact that the throughput of the network is higher, and ETH is actually about 17x faster than BTC, and that's totally ignoring the on-chain scaling that ETH is much closer to than BTC.

Also I don't currently hold any crypto, so you can stop pretending that everyone who is more informed than you is actually just biased. I cashed (of my mostly BTC holdings) in 2017.
