The majority of us have probably only owned one Amel. A lucky few will have upgraded to a newer model. There is much expertise in this group about each model, but I don’t think there is a font of knowledge about comparisons of pros and cons between each model.
I think you need to do some more personal research and then ask some specific questions about the ones you are interested in.
Good fortune with your research. Whatever the result, you will like most of us, be very happy with the AMEL you choose.
