Seiko makes several LEGENDARY automatics, iconic, really. Seiko makes their own automatic movements, which is a big deal in a world of automatics where almost everyone else (except Rolex, notably) uses an ETA or ETA inspired movement like Selita, as far as I know.
I'm not aware of anything citizen makes with that heritage behind it.
Citizen seems to primarily make eco drive and solar movements, which many watch aficionados do not not care for.
