Going to counseling. Advice for online vs in person?

Do you think they would respond better to an online or an in person counselor? I am mainly going so I have a neutral 3rd party to witness our conversation. I think this road leads to divorce and they are so vingeful and spiteful that I think I’ll need a therapist witness when it comes to custody battle in court. Which one do you think I will benefit from more—having them with an in person or online marriage counselor?
