A friend of mine had an aerobatic Yak (54) for a while. He said it was a love/hate relationship - he loved flying it but hated everything that was involved in keeping it flyable, including long periods when it wasn't - up to 6 months. If you want a plane where you can go the airport and "just go fly", go with the Cessna/Lycoming. If you want a hobby that may sometimes let you fly it, the Yak may be a good choice.
