Nex-5R or Nex-7

Hi, if you would have the choice of getting one of these cams which one
would you prefer ???
At the moment I have this "problem" and I really do not know how to
decide.

Hope you could give me some advise...

Here are some PRO of each cam for me.

Pro Nex-5r

• may be better AF

• WiFi

• 16.1 MP ???

• better low ISO

• Picture Quality ???

Pro Nex-7

• Tri Navi

• EVF & Flash can be used together

• Size of the Body

• 24MP (is that really necessary ?)
