z4 tablet or z3 compact tablet?

[killuminati206]

Hey, so im in the market for a tablet. I really like the specs of the z4 but the size of the compact z3. Was wondering peoples thoughts on this. I have a desktop at home and just want a tablet to take on the go. .My main concern is the hardware of the z3 being old compared to the z4. What is the speed comparison between the two. Performance wise is it a huge leap in the z4?? Thank you
