This is as much personal choice as it is anything else. The Sony is sharp, and will look quite good. Generally the tone mapping for HDR content on the Epson is better. From normal viewing distances, most people can't tell the difference in resolution from one model to the next and I'm not sure if you've seen both of these models in person or just through online reviews.
While I would personally lean towards the Epson, I'm not sure how much feedback you are going to get here, and you may have better luck asking this question over at AVS where people have ownership of both models and many have actually seen them both for more direct comparison and consideration of them.
