It all comes down to a personal view on what to mean by flying, as some aspects are different on Microlights and small certified.
I had a friend approaching me with the question, what way to go, last week. For today I had arranged another friend with a Breezer and me on a C172, so we had a direct comparison on same day, similar weather. After 1 hour flying each, we three sat together and he described what he was thinking of.
In the end he is going part-FCL PPL, with four major reasons expressed to us: 1 - the ability to take wife, children and more then a picknick bag in the plane, 2 - the microlight felt too nervous and "light" to him, so he felt less safe, 3 - he was attracted by the 6pot RollsRoyce sound and repelled from the Rotax behavior, especially oil checking and switch off rodeo, 4 - his naive kindergarden view on a plane was served by the old Cessna and not by the almost brand new Breezer.
In the end things are personal feeling and not really bare facts.
