To refresh the tech....

This post regards both phones and tablets so i had to place it somewhere, hope i'm not wrong :S. So i'm in a market for a new gadget, or will soon be, i currently have a Galaxy Nexus (with a cracked screen) and a Nexus 7. I'm thinking between two products, a Galaxy Note 2 to replace my GNex or an IPad 3 to replace my N7. I didn't see Ipad anywhere when i was getting my N7 (i live in Serbia), but recently i saw it for about 650$ on 12 monthly rates. Now i would REALLY appreciate advices from people who have/had iPad 3 or preferably who have both it and the N7, i'm interested which is smoother, overall a better product, portability is not especially deciding factor for me as i don't seem to be carrying it a whole lot. And for the Note 2 also, is it worth getting over something like Nexus 4 or GS3 even which dropped to about 430$ unlocked here...
