I would want to learn to fly in a modern type. The Cessna 152, albeit a well tried aircraft, is the equivalent of learning to drive in a Mk3 Ford Cortina; i.e. it dates back to the 1970s.
Having said that, which aircraft will you be using once you have gained your PPL? In the early days as an inexperienced licence holder you will have a lot to think about and flying the type you are more familiar with can free up a few brain cells for other stuff.
