Difference between Ultra Dual USB Drive and Ultra Drive m3.0

Hi, so basically both of these dual drives have a micro usb on one end and a full usb on the other. Both devices support USB 3.0, both work as a USB OTG and lastly both support read speeds upto 150 mb/s. The only difference is their outer appearance. So, what is the difference between these two. I am a bit confused to which one I should buy. Can anyone help me? I own an LG G3. So which one will be better for it?
