EOS had 28 critical bugs found in less than a month. Let's see how many they find in Tezos. Maybe this will be a good proxy for overall codebase quality. (Probably take 6 months to know for sure.)https://twitter.com/TezosFoundation/status/1010200051837227009 …
Cardano has many interesting ideas but is years out from becoming anything. Last I reviewed the project they still didn't have smart contracts nor Oroubous implemented. Happy to be proven wrong.
