I learnt in a Robin and then bought a Cessna 152! I now switch backwards on forwards between my 152, Duchess Twin and a Senneca Twin without problems.
I think the Cessna is a wonderful aeroplane to fly which takes mastery to fly well. I think they are a great trainer and a good choice to learn in.
I don't think it is difficult to transition to any aircraft type if you have correct instruction. I have always sought out good instructors who have made the move seem easy. I now fly nearly 20 different types including microlights.
I would not have chosen to learn in a 4 seater as there was only me and an Instructor in there, why pay more. Now I often fly with 5 passengers and choose the aircraft that suits the job.
Choose a good school and a good Instructor, try a couple of different types and get on with it!
