You shouldn't look for easier things. Your value comes from your ability to do things others can't do, i.e. hard things. So your question should be instead: "what are the hard problems in back end dev that I think I will be good at dealing with?". Generally I think the hard part of back end dev is all about data, which I consider to be the most important part of any software system, which means you have to do it right. If you are the kind of dev who don't really understand what he is doing, with good common sense and a bit of artistic skills, you can make decent front ends, but back end dev is not for you. If on the other hand, you like to get to the bottom of things but feel overwhelmed by all the mess browsers throw at you, you will be better at the back than on the front. Really, is is not about easy or hard, it is about finding something you are good at.
