Which one should I go for? Go or L7 ?

I already have l7 , and i think is a great phone. Fast enough, large display, strong battery , but the best thing of l7 is its 4.0.3 andriod.

the L7 has bigger screen (4,3 inch) and the go has an 3,5 inch screen the L7 has android 4.0 while the go has android 2.3

the processor of the l7 is 1GHz single core while the go has an 1GHz dual core

the screen type of the l7 has IPS-LCD and the go has only TFT

the screen resolution of the l7 is higher and the camera can record in full HD (1080P) while the go can only record in HD Ready (720P)

the battery life from the l7 is stronger 

so i think you must decide it for your own

if you want a bigger and better screen then the l7 is a good choice

but if you want a more powerful processor then you should go for the xperia go

also keep in mind if you want to install the newest and strongest apps that a single core would be very slow sometimes
