Default Whats the easiest way to root a i337 with mk2 4.3?

I have a at&t i337 s4 with android 4.3 mk2 & I need to root it so I can get my safestrap going for my custom rom of choice..I lost root & last time I was running 4.2.2 & used kingo root..I tried that today but it was only good up to 4.2.2 not 4.3 from what I gathered..so whats the quickest easiest way for me to root now? I've done some research but found alot of confusing & conflicting results so thought I'd just ask here on xda where I've never been done wrong..thanks
