#3 Currently the biggest option available to any non-WWE Superstar
It's a great time to be a professional wrestler, because of the multitude of options that are available to any performer, at the moment. While he/she always has the option of working for Vince McMahon, there are so many other possibilities for one to choose from.
Not only can Luke Harper choose to go to Impact Wrestling, which has been making strides, I'm sure NJPW or ROH would also be thrilled to lap him up at once. The NWA has also been making waves recently, and Harper would certainly be a great fit there, if it comes to that.
But all said and done, AEW is clearly the second-biggest option available, touring across the length of America with a dedicated fan base across the entire world. While an AEW Superstar may not necessarily have the same degree of worldwide fame as say someone at the top of the WWE food chain, it is a fast-growing company that is making waves across the world.
As with anyone pursuing a career, Luke Harper will want the best possible option available to him and that is AEW!
