I've been to Arrowhead Pond for various events...but my best experience has been to see a Mighty Duck hockey game. The atmosphere is always exciting, although it does get really, really loud in the place.
There seems to be a lot of adequate parking for the facility, but of course, it is always a ridiculous price.
They do have a lot of concerts in the building, so it is the Orange County equivalent to the Staples Center in Los Angeles. It definitely has a newer look to it, and seems to be very well maintained and landscaped.
If you don't want the hustle and bustle of Los Angeles to check out your indoor events and concerts, check them out in the OC at Arrowhead Pond.
