I've always used Times New Roman, and haven't had any complaints yet. (But if I knew a certain editor hated it, I'd switch the font before submitting.)
The trouble with Times is that you almost never do get complaints. Editors seldom complain about anything. There isn't enough time in the day to do so. But not getting complaints does not make Times any easier to edit. Try inserting proofreaders' marks into a page of Times, then on a page of Courier, and see which gives you a headache.
Courier is the standard, and just because editors don't complain does not mean it doesn't bother them, or doesn't affect the way they read a story.
Some things fall into the area of "The writer should know this." Complaining doesn't help anyone, takes too much time, and is wasted effort.
