The optical view finder was superior back when LCDs were junk. I would say they are about even now, and LCDs are getting better all the time, while optical isn't. The LCD has the advantage of showing the results of exposure compensation. I've always thought the swinging mirror was a workaround that had run it's course.
As Dbump said, if you have a static landscape scene, you can take a picture and REview it and adjust and try again. To me it seems clunky to have to be hunched over trying to squint through the viewfinder.
