And always the big benefit of the modern tools is that it doesn’t destroy all the highlight data that is there but is too bright to be visible.
I think a normal old curve tool will destroy everything over 1.0 before filmic has a chance to map it.
If you use them after (above) filmic it’s OK, but for me you might as well use TE.
I also like that it starts as a flat horizontal line instead of a diagonal line up. I know this is against the convention, but for making adjustments it makes more sense to me. Easier to see what is happening at every point (making it brighter or darker).
And apparently it’s better at preserving the correct chromatic representation when the brightness changes, but my adjustments have never been too strong to notice that.
