I think a stronger brand name. Also on macOS I found Docker Desktop to be more straightforward. Also lately it has been very error prone. Randomly failing at mounting files, or cleaning up networking rules, or suddenly becoming bog slow so I have to restart the VM.

Podman on macOS feels miles less refined. Orbstack is a way better choice.

I only use podman on Linux and there it is blazing fast. Even so, most features seem to be geared to be able to replace kubernetes in combination with systemd. And then something simple as docker compose support is flaky and it’s TUI/ux lags behind the original.
