y ppl disapprove u?

both are compact-ish, similar but yet different in many ways. hard to say which is better, more to own preference.
for me i own a Nex 3, great but i wish to have the micro 4/3 many2 lenses and accesories . limited lenses & accesories for now but still good enuf for me 
and another thing, no remote shutter (non ir/wireless) for nex to play bulb long shutter mode 

try look at here (http://snapsort.com/compare/Panasonic-GF3-vs-Sony_Alpha_NEX-5)
very good site, compare by specs and not biased 
spam some from my nex3 at the Malaysia vs Singapore last thursday 
pair with pancake and sal35 f1.8
