My impression is that `writeln` is more common than `writefln` in 
D code, and a quick grep of Phobos supports that impression:

$ grep -R 'writeln' std/  | wc -l
321
$ grep -R 'writefln' std/ | wc -l
225

Obviously not scientific, but at the very least it shows that 
formatted output is not the clear and unambiguous winner.
