Choosing Roux turned out to be a great cubing decision for me. I started only a couple of years after Gilles Roux first posted his method. At that time it was only me, Kirjava, and a couple of other people using Roux. So resources were scarce. The only one was Gilles' website. While an amazing site, it still required a lot of figuring things out on my own. That self reliance helped me to gain an understanding of blockbuilding and other concepts of the cube. I don't think I would have gained that so easily with CFOP.
There are valid arguments from all sides. Do what you enjoy and you'll find your way.
