X4 vs X3 actual experience comparison

I've been using these 2 devices for quite some time now and here's my thought and my verdict on which one you should buy...

Size: Both devices run Crossink. As you see, my language Vietnamese. The X3 is smaller and the display shows about 3 lines fewer. In reality, I find reading on the X4 more comfortable due to bigger screen and the X4 fits my hand better.

Display: I don't see many people mentioning this but the X3's screen definitely looks better. The white looks more "punchy". Contrast on the X3 is definitely better. Texts are a bit sharper too. And the X3 is less gloss too. As you can see my reading light show clearer on my X4. 

Portability & connectivity: X3 wins of course. It's quite thinner and lighter. However, I do find the magnetic charge inconvenient. Like when I want to flash it, It's frustrating that I don't have the magnetic cable with me. Battery lasts long though.

The lanyard holes on the X3 is a lot bigger and much easier to put on the lanyard.

Overall I like the body ratio of the X3 better since it's less tall and more like a reader. And the bezel is slimmer. I just got the X3 after buying the X4 in February. I do think the X3 is a bit too small. At first I used the X3 all the time but lately I switched back to the X4. I like the buttons on the X4 better. I'm not sure it's my units but it's worth mentioning that the buttons on the X4 are clickier and louder. The X3's buttons are somewhat mushy and quiter.

Overall If I have to choose 1, I'd go with the X4. However, I probably will abandon both once the S4 is released.
