TryGetNonEnumeratedCount is always efficient, but that's because in the case that the enumerable doesn't already know its count, instead of falling back to counting elements one-by-one (as Count does), it just gives up. It is Count but without the default/slow path, only the special cases. I wouldn't really call it "more efficient", it's more like a niche thing that you can use when you would like to have a count but you don't really need it (such as to create a collection with an initial size, which isn't worth counting one-by-one for, but if getting the count is basically free then you may as well use it).

Any can certainly be more efficient than Count, thanks to the early-out. In some cases Count is actually more efficient, but let's put that aside, that's not really relevant to the case you're dealing with.

So far I have no specific reason to think that there is any better solution than Any. Maybe if there is some special property of the Mystery Function that's being called, or of the overall algorithm, there may be some other technique.
