It is very simple choice for me. It will have to be a 3448. But it also must be a right 3448. Not all 3448 exude the same charm as the case and the dial play an important role. 3448 is a vintage piece and so it should have that charm. If it is too minty, it feels weird. I also like 3940 first series and 5050. Is 3448 better that them, I am not so sure. Best is to have all 3 :P, But between the two choices that you have chosen, 3448 wins hands down.
