An environment variable can be set different for each process,
it keeps its value as long as the process runs, and it can be
automatically inherited by child processes.

In contrast a "-o foo=bar" option setting must be either specified
again and again for each job submission or it is stored for all
processes of a user in a file in his home directory.
