Illustrator's anti-aliasing is very dirty and very-very dark. I personally work mostly on icons in Illustrator and the reason I avoid the application for say simple UI is that the result will be dirty. If I import my illustration from AI to Photoshop or Adobe XD - the whole layout will become much cleaner, lighter on preview and on export from there.
Recently I've encountered a situation when my colleague had a small circle, and for this circle, the stroke's been defined as black and the fill was transparent. In Illustrator it looked like the circle hadn't a hole in its center (because the stroke was wide and the circle itself was small) but in any other application (Ps and even Safari and Sketchapp when exported as .svg) the hole was big and obvious.
See, I can't show Illustrator's export results to my clients, especially on pitches: my layouts will look dirtier than other persons' work. It will look cleaner even if I open illustrator's file in Photoshop and export from there. But it solves the problem on an export stage and not when I'm editing a file. So it's a real problem.
It would be lovely if you implement in Illustrator the same anti-aliasing mechanism as you already have in Adobe XD or After Effects.
