We did a few phone visits when weather was bad and have done video visits when one or the other of us is traveling or when I was recovering from surgery. Most the time we are in person.

For me phone is better than nothing, video better than phone, and in person the best. Email sometimes is just as good as phone.

I would agree with what others have said, might or might not work all depending on what issues come out and how the in person chemistry translates to voice only interactions.
