Were you expecting any?

The contents of eventname (if an array) or the contents of the memory
it points to (if a pointer) will be the same for either statement in
this example. This would not be true if the second argument contained
anything sprintf would consider a conversion specification.

strcpy returns a pointer while sprintf returns an int but, since
either will be discarded, I don't think this is a relevant difference.

I would expect strcpy to be significantly faster but this is my
intuitive judgement and not part of the standard.

The only real difference I can see is that you need to include a
different header file depending on which you use.
