Tough call. Comparing the bundled lens options I think I'd go with the Sony 5N. However as an ecosystem I'd prefer the Lumix since the micro 4/3s spec opens up more lens options (particularly wider aperture lenses than Sony's current lineup). Sony has never been good at leaving the "Proprietary" sandbox; meanwhile the Lumix is compatible with some competitor lenses and third party manufacturers like Lecia.
If you get the kit the 5N is great. If you plan on expanding to specialty lenses go with the Lumix.
