For the price..... either of those bikes will make you very happy, so long as they don't have some sort of lie hidden in the post somewhere. I mean, they both say they are freshly tuned up and ready to ride. Either way, you to need to inspect the gas tanks for rust and the vacuum lines for deterioration. Also check the condition of the tires. Any sidewall cracks and you need to keep negotiating.
Based on what you are saying you need, I can't think of a bike better suited for you than the Vulcan 750. It's not get-in-trouble-fast. It's powerful when you need to avoid something strong. Great bike.
