Give AcDisplay a try. I've tried just about all of the lock screen apps I can find and have found this to be the most complete offering. It's a little like the MotoX lock screen and does a very good job of showing all of your notifications at a glance. One essential feature for me is the ability to skip and pause music from my lockscreen and most applications don't have that functionality, AcDisplay does. You can also unlock by swiping anywhere, instead of having to swipe up or down, or left to right in a specific spot; just swipe anywhere and it unlocks. Honestly, in my opinion, there is nothing out there that comes close.
