It even seems that (1234) + '' may even be slower than (1234).toString(), which seems strange.

why should that be strange?
(1234).toString() does two steps:
- coercing the number literal into a Number onbject
- calling .toString()

(1234) + '' does (at least) 3
- coercing the number literal into a Number onbject
- calling .toString()
- make the concatenation

toString() was faster in Chrome but was slightly slower in IE when I performed brief tests.
