I've tried the default curve (i.e. no curve) with a variety of DPIs and HIP sensitivity. What I found is that you need to go down to 5-10 with the default curve to avoid the jitters.
I then tried Henry's curve, and no matter the mouse sense, no jitters. I, however, have turned aim assist to 20, and use HIP sens of 9-10 and boost at 50 with steady aim. I have not tried humanefemale's curve, yet.
I wonder two things:
(1) with herny's curve, should you have aim assist at 70-80, or not. I've tried it both ways, and can't tell a difference. From what I've seen about OW aim assist, it seems like it may hurt trying to tract targets. Does anyone have any anecdotal stories that they can share about this?
(2) how is humanefemale's curve vs. henry's curve with heroes like Genji, and Tracer?
