Well CC offers more than CS since it's bigger.
We have a minor league Hockey team...CC Rayz, and AA Affiliate of the Houston Astros...CC Hooks baseball team.
There are ample amount of restaurants for sure and depending on what kind of nightlife you like, there's some here.
There are several live music venues and some big names come here but not as frequently as San Antonio, Austin, or Houston. If you like the country music in CS then you'll see them pass thru here...Stoney, Wade Bowen, Randy Rogers, Pat Green, Kevin Fowler, Ragweed, etc.
I grew up in Corpus, moved away for about 10 years, now have moved back and, to me, it's pretty much the same place it was 10 years ago, with the exception of the CC Hooks, and I'd much rather live in San Antonio or Austin, but that's me, who grew up here.
If you were in your 30's and single I'd say it'd be questionable to move here if you were looking to find a mate, but since you are married, I think you'll find it a pretty decent place to be.
If you like water sports you'll like it here. People give the beach a bad rap because it's not tranquil like the Virgin Islands, but I love the beach and you can have a ton of fun on the water. Port Aransas is only 20 minutes away and a blast in the summertime. Fishing, boating, sailing, surfing, kiteboarding, etc, you can do year round. If you like to hunt, and know someone, the hunting is not too bad either but a lot of the game has been depleted...unless you like hunting hogs.
