Of course, in the end it really boils down to how the agent makes you feel. Does the agent confidently tell you that he can sell your home in a few months? Or does the agent exude an air of uncertainty, making you wonder if your home will ever sell?
Pick an agent you feel comfortable with. The agent will be your partner for the next few months or so. He will be your advocate in the negotiation process, your walking, talking encyclopedia when the paperwork comes in, and your representative all throughout the process.
