Performance of LINQ Any vs FirstOrDefault != null

Question

There are multiple places in an Open Source Project (OSP) code I contribute, where it has to be determined if an element in a collection satisfies a certain condition.

Answer 1

The enumeration in Any() stops as soon as it finds a matching item as well:

I would expect the performance to be very similar. Note that the FirstOrDefault version won't work with a collection of value types (since the default isn't null) but the Any version would.
