Ok in that you do have something. The Sm. 79 was a bomber design that like other older designs moved to shipping. So let us take one at a time if you like.
ok. I could agree with you about that, as it was used in as much as they good and the only other one I could think of was the MC 202. The fighter did ok, but was not that great. The 79 did have some good kills on shipping, but it never got the fighter support or the number of planes to do great things. Also the design was getting old.
I am not a big Bieplane lover myself, but if you like it gosd for you. I am not shure of the "best looking" bit. As a lot of Italian craft had good lines.
I think some of the trimoters are very nice. At first I did not like them that much, but they have grown on me a bit. The Do.24 is a good one and it had a very good war record.
