Yes PREFERENCE is completely irrelevant when the OP asks about what’s a good bike to learn on.
I’d prefer to fly on an F22 raptor over a Cessna as well as the next guy, unfortunately logically it’s not smart.
Oh and for the record, keep in mind that in Europe you are mandated to start on a small CC and move up through the classes.
I’m sure there is some slight logic behind that.
Nobody LIKES to start out on an ugly, old, dated, carbed 250. It’s just the smarter way of doing it.
