I guess I fall in line with most people on the forum. End the freakin' vomit saturated tonemaping and edge glow. Next be mindful of the dynamic range. If you try to fit 30 stops of DR on a computer screen it looks fake. Shadows should be dark and highlights should be bright...
I don't see anything wrong with taking several pictures to enhance the dynamic range of your camera. However, it can be hard to get a balanced end result.
To the purists, shooting with a graduated filter is HDR so I don't get why you're getting your panties in a bunch...
I'd use it for video or 135, but never for landscape... okay... maybe a one-stop filter, but I'd have to go to photographers' confessional. Of course ND grads are HDR. I used to quite like ND grads, but they compensate for small format and bad light rather than enhancing the scene, at least more often than not.
