You're posting this in r/cincinnati...most people will be biased towards the Queen City. You should probably post the same question in r/columbus and see what they have to say as well. I have also lived in both cities and find Columbus more friendly for young adults. While neighborhoods like OTR are awesome and growing in Cincy, The Short North is much more expansive and has A LOT more to offer. Columbus also has a bigger downtown and the public transportation is great (better than Cincinanti's IMO) because High Street acts as the central vein of much of the city. Columbus also has more of a liberal attitude if that's your thing. The Arena District is also filled with with many bars and young professionals looking to have a good time on the weekends. I like both cities but I feel like Columbus is a better fit for you. DESPITE all of this, Cincinnati is slowly growing in terms of becoming more friendly for young people and will prob be a much different, more awesome place a few years from now. Just saying.
