Thank you for your question. Here is my perception:

Liquid

- 🟠 All fee goes to Liquid Functionaries (15)

- 🟠 Any combination of 5 functionaries can paralyze the Liquid

- 🔴 After two weeks (I think) can Blockstream steal all the Liquid funds

- 🔴 Liquid is vulnerable to governments

Ecash

- 🟢Fees are decentralized

- 🔴 Any mint can steal the funds

- 🟢But there can be huge competition - anyone can run a mint

- 🟢 Users can withdraw their funds anytime - immediately → unchain or on lightning

- 🟢 Ecash brings new value → can be shared with anyone - without previous action - for example via message

- 🟢 It enables simple interaction with Lightning Network
