Totally agree, but it helps to prove your point if you're using accurate data. You described Ethereum as having 7 tx every 2 minutes, when it's actually 210 every 30 seconds.
Don't forget that there's a lot more you can do on the Ethereum blockchain than on the Bitshares blockchain.
Edit: Also, as far as I can find, the highest tx/s I could find for Bitshares is 333 tx/s under stress testing.
