Other temples I've been to are either silent or have a recording of monks chanting.
I'm not sure if today was special, but we were treated with a live "performance" of some chanting. For my gf and me, it has so far been a unique experience.
I think the east temple may have been a little more impressive, architecturally speaking, but I would hate to have to choose between them if I only had time for one. Go see them both in person; the pictures don't do them justice.
