It depends on what you’re looking for. Most people use containerd as their backend to Kubernetes. Docker itself uses it. Podman uses a different engine. That may matter to some folks.
There are also a bunch of tools that talk directly to the docker socket.
I think the most surprising coming from docker was that containerd can’t build images, just run them, thus nerdctl and things plus other userspace ways of building images too.. so many options..
Totally makes sense when you understand more but initial is surprising.

There are a lot of varying use cases here.
