My thoughts:
1. The 339 is a work of art -- far and away the best in class!!!
2. The 351 is also a great piece -- beautiful brown dial, gold hands and Ti case -- reasonably priced -- readily available non-SE -- a real winner. I love the fact that Panerai has increased its production of brown dials, particularly in Ti cases with gold hands.
3. The 348 is a fantastic looking watch. That being said, it is antithetical to what I know as Panerai.
4. The 300 is also great looking, but at 53mm, unwearable for most of the general public (me included).
Thanks again for the great reporting!!!
