Been really using Venice. UI is clean, I like the live counter while waiting for replies or images, it's small but useful. The replies come in fast without the usual filters you see elsewhere. It's more to the point, feels casual and doesn't waste your time. Good pick if you just want something straightforward without the privacy trade offs.
