I have a couple of bipes, an E-Flite PT-17 and a GP Curtiss. They takeoff relatively quickly without near as much power supplied to the motor as compared to monoplanes. They are difficult to keep from flipping over when landing, which I hate. Definitely a ton of fun and I am glad they are part of my collection. Flying is similar to monoplanes, landing them without tipping it over is a challenge for me. It's definitely easier to do loops with them. I would say to go for it, you will not regret it.
