Whos leading? Apple or Samsung?

So guys, this question has be bothering me alot lately. In the start of the year my parents told me I could choose between an Iphone or a Samsung. I have been searching about new technologies, which one is better but I am really in doubt. You see an Iphone is very complicated to use it. "Of course if you get the hang of it, then it's even better". Even though it's complicated it offers you more security. While Samsung its easier to use but you can't be secure a hundred percent. Of course I am talking about new generatios of technologies, the likes of S4 and Iphone 5S. So I am blogging to you guys that are more into this than me. Express your knowledge with a coment helping me out. Thankyou :)
