Thanks for clarifying my opinion to me. I probably should have better defined the use of the terms legit and prestige. OSU is one of the few universities that offers an online MBA that is AACSB accredited (details here https://www.aacsb.net). The stricter accreditation standards legitimize and bring prestige to this program in the eyes of potential future employers. No, it is not a top-20 in-residence business program, but at least it follows a baseline standard of behavior and imparts the expected skillset to its graduates. That's far more than you can say for certain other online MBA programs. I personally went through a similar program at a different university and found it far more challenging than the work demonstrated by my peers in "check the box" programs.
It all comes down to your goals. If you want to JUST check the box to make Major, get a check the box degree. If you want something marketable, get a "better" degree. If you can somehow swing a top-20 in-residence program within the context of your family responsibilities combined with your personal and career goals, do it.
ETA: I just looked up the UNC Online MBA you mentioned. Looks great, but could be a little expensive at $91K
