Round vs. Square ND filters for long exposures

Over 82mm I well understand using square filters. As to GNDs, they are now totally obsolete, as what they were intended for can now be achieved digitally with infinitely more control, unless you are shooting video.
Obsolete? Only to an editor, I personally am still a
photographer. And all my GLASS square filters are fully coated. Nothing compares to a properly shot image.

Please check your sources. PLASTIC filters have no MC, all my GLASS square filters are fully multi-coated.

Taking two exposures a couple of EV apart, in much less time than it takes to properly set up a GND (which I used for years) sets the stage for something GND users can only dream about. In moments in Photoshop, these can be aligned on two layers, At that point you have an infinitely customizable gradient transition in terms of shape, position, transparency and feathering. All non- destructive--it can be redone as many time as you would like.
And that is just the beginning. You can then independently process the two different parts of the image to optimize exposure balance, saturation, shadows and highlights, contrast, color, you name it.
I had a full set of Tiffen 4 x 5 GNDs for work, 0.3, 0.6 and 0.9, soft and hard transitions, and as soon as I found out what PS could do I stopped using them altogether. Not only are they expensive and a pain to carry around, it takes time to set them up, the image is at least slightly degraded by a fat piece of glass in front of the lens and the transition is always a compromise. I have yet to find anything toever again use a GND.
