Of course it is preferable.  The idiom constitutes the language's direct

an extraneous always-true expression.

Using for (;;) for an infinite loop is an abomination.  Anyone

 I can't believe we're still having this conversation.
 Surely, on any reasonably modern compiler, all three forms will generate
exactly the same code.
 

I would think so, yes.  (I've used toolchains where that was not true, but they are firmly in my past.)
But conversations - arguments - about style of source code /never/ get out of date!
Personally, I'm in the "while (true) { ... }" camp.  To me, "for (;;)" looks like a weird smiley, and I do not fall for any appeals to Deniis Ritchie's authority.
But we are missing another option:
void mainloop() {
// do something
mainloop();
}
That should be fine with an optimising compiler.
