I have a neon which my neice is rf in at 2 and 2 tilt and adjusts for my twins that my older boy was rf in til almost 3. Both great seats. The neon/kompressor is more upright/compact with rf. I prefer the tilt and adjust method of adjusting the belt and the fabric and seat belts 'feel' better/thicker/nicer on the tilt and adjust but otherwise I love both
