Else use List. You birey't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List not an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"
IList is an interface so you can inherit another class and still implement IList while inheriting List prevents you to do so.
Here's an example: I had a project once where our lists got very large, and resulting fragmentation of the large object heap was hurting performance. We replaced List with LinkedList. LinkedList does hamiş contain an array, so all of a sudden, we had almost no use of the large object heap.
