Don't know a ton about MBA specifically, but I've been a professional in higher ed for 30 years. Online programs were mostly ****** diploma mills designed to vacuum up government loan money through the 90's, and were pretty much the mark of the beast when they showed up on your transcript. The feds cracked down on that big-time in the 2000s, bringing in a set of criteria necessary to qualify for fed student loans that put most of them out of business (thanks Obama!).
At the same time, traditional student numbers started tanking, and are on pace to continue to fall off a cliff. As a result, a lot of good schools, including many state schools, recognized the need to offer educational programs to non-traditional and adult students who don't have the ability to attend full time on-campus. So, we're now at a point where there are a lot of high-quality online and hybrid undergrad and graduate programs available, often offered by well-regarded state and private institutions, taught by the same professors, where the degree is equivalent to what you'd get from an in-person program.
Evaluate your options based on your purpose for the degree. Are you just needing the letters, or is there specialized knowledge that you need to make the next step? How well is the program ranked, particularly for your specialty area? For example, an MBA from UT Knoxville is fine, but their MBA logistics program is considered top 5, so if that's your field a degree from there will carry some weight, and people in the field would likely both understand that and may have a degree from the same institution, which can be a good thing. Talk to a few people who are doing the work you want to do and get a feel for what kind of credentials they have, and to what degree those were instrumental in them getting to that position. Good luck.
