`map` vs `broadcast`: should one prefer `map` if these are equivalent?

Earlier thread on same topic:

When to use broadcasting with . vs map

If I want to apply a function across say a Vector in julia, there are two ways I could do it: map(f, seq) f.(seq) Is any way “better” than the other? In fact, is there any difference in the implementation between using map and broadcasting with . ?

I wonder if this is an intrinsic limitation because broadcast is a more complicated operation, in which case developers should be encouraged to prefer map if that’s an option?

That’s the way I understand it, at least.

The Julia Manual actually even says that . isn’t required for performance, but that it’s convenient:

In Julia, vectorized functions are not required for performance, and indeed it is often beneficial to write your own loops (see Performance Tips), but they can still be convenient.

Also to note: there are subtle performance considerations to keep in mind when using broadcasting:
