Sorry, never tried that.

Generically speaking C makes it easy to interact with the computer memory but harder to abstract things while OO languages have it reverse.

C has GOTO, Objective-C not.

Objective-C has objects that easily can encapsulate different aspects of your logic. Objective-C is very verbose and readable while most C API's aren't.

Obviously Swift is even better in that regard as it has better types and checks but it doesn't allow you to seamlessly use C.
