Recursion is slower and it consumes more memory since it can fill up the stack. But there is a work-around called tail-call optimization which requires a little more complex code (since you need another parameter to the function to pass around) but is more efficient since it doesn't fill the stack.

Unfortunately C# does not support this so I would suggest you to use recursion with care, because you might get stack overflow for large values.

As a conclusion, in functional languages you only have recursion and have to deal with it; but in imperative languages iteration is more natural and more efficient. The majority of the most-used imperative languages either does not support (Java, C#, Python) or does not guarantee (C, C++) tail call optimization.
