The official graphs are the only accurate graphs:
I think the ER4SR is supposed to be more accurate through the mids (they do sound a bit too warm).
There's the user johnyang1997 who appears to be very knowledgeable who says there are FR differences in the treble and linked to this graph (source: https://clarityfidelity.blogspot.com/2016/10/etymotic-research-er4xr-iem.html):
Apparently he has done work with Topping and Moondrop so his comments have a bit of weight. He seems to prefer the SR. I'd like to try the SR and compare to my XR. But then there's the trouble of selling and shipping the one I don't like, or I could keep them both.
