I love the G550JK for the :
Looks.
Balance between price and performance.
Price.
Red line.
IPS screen. (Sick of the TN on my laptop)
Black and red theme.
Backlit keyboard.
I love the 1440p display. It might not be the best but hey LG are moving things in the right direction. I also love how small the bezels are and how the back doesn't look like plastic but is. Overall a great phone (note opinions vary)
