Haven't tried it in a while, but, last I checked, Word Equation Editor output didn't look serious because it looked janky and look like it wasn't really done in a "professional" tool. Part of that is a self-fulfilling prophecy of course, LaTeX output looks right in part because it's what people have been reading for decades, but TeX's formulas just look plain good.
I would be willing to try again, but I'm not buying Word for the privilege.

It produces documents that look like those produced by professors, and luminaries in the field. If you write equations in Word Equation Editor, your work just doesn't look very serious.
It's the same joy I felt when I laser-printed my first newsletter designed in Aldus PageMaker. I was only in my teens but I felt like a "professional".
