Yes, but the other 1W members don't have FFP's that they share with a bunch of other airlines who are not members of 1W.</font>
Not sure it's a relevant point. For instance, you can yet accrue miles on SR and ASIANA if you've enrolled into AsiaMiles (CX FFP), and on SR if you're part of AAdvantage on certain routes (indeed good reasons for SR to join OW). Plus members of BA ExClub too can accrue miles on some exotic airlines not members of OW.
To me, being part of OW would be a big advantage for Swiss and Qualiflyer (needless to say qualiflyer members as well), * not a very intelligent choice considering LH and OS. And Swiss, please don't do your first mistake (and the last one I'm afraid) by joining SkyTeam !
