Superzoom - Oly 14-150, Pana 14-140

My first M43 camera was the GH1 with the 14-140. Great lens especially for video [silent focus] but as stated it is heavy and big. No longer have the GH1 but kept the 14-140 and use it on occasion with my OMD when I know I will want more reach than the 12-50. But, if I did not have the 14-140 to start with and was in the market for that range zoom I would most likely get the Oly for its size weight. I also have the Pana 20 and 100-300, both of which I have very high regards for.
