Although they use the same technologies to implement containers, such as kernel namespaces, cgroups, and overlay filesystems, the two have totally different purposes.

Docker containerizes applications. One of its main promises is the old “write once, write anywhere”. Docker allows you to build your application in containers, either from scratch or on top of other applications. The latter may be the main reason for Docker’s success. Another is probably the Docker hub, where everybody can publish their applications, and everybody can download and use applications as fundamental building blocks to create new ones.

LXD is great for running very resource-efficient virtual private servers, full (or almost) operating systems in containers. It doesn’t have tools for building container images, as far as I know, and doesn’t have anything like the Docker hub.

Thus, you can’t say that one is generally better than the other.
