First Time FF User - 5DM3 or D600?

Thank you all for the very helpful feedback. Sadly i'm still torn.

Option 1:

5DM3 + 50mm 1.2L

Option 2:

D600 + 14-24 2.8 and 50mm 1.8G.

I know a lot of you recommended holding both cameras, which i have done in store a few times. Though the 5D is significantly larger, they both feel quite good. I dont have overly large hands, so both work.
