From my standpoint, the Sigma is better at shooting people and has FAR less breathing issues, but it is not as optically perfect as the Samyang, which is far sharper and has no barrel distortion. On the crop of the GH2, the 35mm makes less sense than it does on aps-c and even less than on a 5d (which I find it looks great on). The sigma doesn't have a dedicated aperture ring, but I do have a Novoflex Nikon to m43 adapter, so I'm personally all set to buy the Sigma, if it is ultimately going to be the right move...I know that, while there is a lot of focus breathing involved with the Samyang, and it isn't the best at shooting people in a 'naturalistic' kind of way like the, it does look great as a general composition tool and would probably end up taking optically better photos with.

Right now I have the tamron 17-50 f2.8, a minolta 24mm f2.8 (which I'm thinking about selling dependent on which lens I'm getting), a SMC 50mm and a Nikon 85mm f1.8d. In many ways, I wish I could just buy each of the voigtlanders and call it a day, but alas, I haven't sold any organs on the black market, yet...

How do you guys way in on these two lenses? Do you think there's a lens in this range that I have't considered enough of yet? I'm also thinking of going with the 25mm leica f1.4 and getting the voigtlander 40mm to go with it, but so far I've just been really enamored with both of these lenses. Any help or suggestions would be greatly appreciated!
