Being you are in Ohio I would chose vapercon. It is one of the bigger conventions if not the biggest I do not have the attendence numbers in front of me . Also all the big name reviewers attend if you are interested in meeting them. The most important part is the distance I am in central pa and it is a easy afternoon drive for me with it being in Richmond Va. You can not beat the cost savings of being able to drive instead of fly. In the end it is up to you. I have heard people having great times at all the major conventions. I would not say any are worse than others. One piece of advice I can give you at the meets is don't be shy. I have not meet a vaper at a meet that was anything less than friendly and very willing to talk. We are all there to meet others and have fun.
