Top-tier business schools sometimes have "Evening" MBA programs. They take about 3 years to complete. At the school I went to, the Evening MBA students were more highly regarded (by employers) than the full-time MBA students. They were more mature, had more work experience, and had demonstrated a willingness to work harder for longer.

There are also "Executive" MBA progams which are shorter programs. I don't know much about those.

I'm fairly sure that an Evening MBA from a recognizable top-flight school (like, say, Columbia) will have far more value for future employers than an online MBA.

The question, though, is how much value do you really need and how much time and money are you willing to put into it.

I'd say, first critically examine why you are considering getting an MBA in the first place. The rest of the analysis should flow from there.
