I think you mean Whispering Canyon (WCC), so I will give opinion based on that.
Atmosphere
Whispering Canyon - loud, rowdy. Kids do stick horse racing, wait staff yells at you and does funny things, like bringing my husband a jar that would hold about a 2 liter drink when he asked for a refill on his diet coke. DD(7) enjoyed it, me, not so much, but that is a personal opinion.
Ohana - quieter, calmer pace, but still had the kids come up and dance around the room, do the limbo. DD, DH and I LOVED it!
Food
Whispering Canyon - we got the BBQ skillets and the food was plentiful and good, just not great. Also, our meal took a long time. I kinda felt like I was waiting on my food
Ohana - One of the best places I have eaten at WDW (we are going back in May). Everything we had (the shrimp, the skewered meats of turkey, pork, steak and sausage) was Fabulous! DD almost ate herself sick on the sausage. We had to beg them to stop bringing us food. The dessert was THE BEST dessert I have had at Disney!
Service
Whispering Canyon - As I said, part of the "charm " of the restaurant is the waiters are loud and play tricks.
Ohana - very gracious staff
So, isn't it obvious, my vote would be O'hana, but that depends on what kind of "experience " you want.
Hope this helps!
