A99 or EM5?

Hi, I originally was about to buy the Olympus EM5, but at the store I tried the Sony A99 and I fell in love with it. Besides, I live in Mexico City and the price is about $1791 USD(almost 1000 less than Amazon) and the Sony 50mm FF is only $223USD. (20 months no interest)

So, now I´m thinking seriously in the A99, but I have some doubts:

-Does anyone here own boths cameras? Can you tell the difference in IQ and usability?

-I shoot my family and street photography, but when on vacations, I love landscapes. You can see some examples here: https://plus.google.com/photos/110026590902741006652/albums/5649230299307243873

(I´ve just sold my Nikon D40x used in those pics)

What camera would you recommend for this type of photography?

-I have heard that a m43 lens of 25mm f1.4 equals 50mm 2.8 in FF, that´s a limit for me, as I loved my Nikon 50mm f 1.8 and would like a lot an f1.4. Do someone has practical experience using both lens? For example a Summilux 25mm f1.4 and the Sony 50mm f1.4?

-How good is the EM5 for wide angle nature and city photography? Anyone has some samples?

-My little daughters practice ballet, do someone has examples of the EM5 inside theaters or low light?

Regards,

Omar
