Filesets are more heavy-weight entities that have names and persist
across Emacs sessions.  OTOH, a set of marked buffers in the buffer list
is more quick to use and is transient that vanishes with killing the
buffer list.

I think we should not require from users using only persistent filesets.
We should provide both tightly integrated, with the buffer list
having commands to turn a transient set of marked buffers into a fileset
and vice versa.

Moreover, I think that all project-like packages (like recently discussed
packages that group a set of files into a project) should use filesets.
