Here's a recent video in which I compare Photomatix to Aurora HDR. I used Photomatix for 5-6 years to build my HDR photos, but once I started using Aurora HDR, I never went back to Photomatix. I find I can edit my picture completely in Aurora HDR whereas with Photomatix I can build the base HDR and then I pretty much have to go elsewhere for stylizing touches and more. So I find it less efficient and a bit cumbersome, really. Follow along in this video and watch me compare the two. Let me know if you have any questions!
