I think Im defanitely in the minority but my family didnt like Kona..
The famous tuna oscar was dry and tasteless, my DH and DS steak was grissly and seemed cheap. DD shrimp and scallops seemed ok just wasnt alot on the plate.
Dessert was great tho..
Ohana we love everything about it except maybe that it can get quite crowded
The salad, stir fried veggies, potstickers, wings, grilled steak, chicken,shrimp are very good and the bread pudding is to die for and Im NOT a bread pudding fan normally..
I say you should try every place atleast once so if you can do both do it!
By the way I hear amazing things about Kona breakfast so maybe do breakfast there and dinner at Ohana?
