The issue with Tezos is, there is no reason to suspect they can handle the transaction volume any different than ETH does. EOS will basically blast past all transaction volume limits, and permit features Tezos does not have. Aeternity claims scalability so it is worth looking into, but then I would still suggest the asynch nature of EOS makes it better. And it actually looks like Aeternity cheats to achieve consensus thus allowing scalability. Consensus happens off-chain, and only if there is a dispute does it get forced back into the blockchain to resolve.

It's a clever trick, but why not just have consensus on-chain and also scale? Mr. Dan is the only person seemingly smart enough to pull this off, so his project is the way to go, especially since his last two projects now trade into the top 15 regularly.
