I have used both extensively and I prefer AeroSpace.
Multi monitor support is the killer for me, but there are other small wins.
When you move a workspace in Yabai to a new monitor, it changes it's ID so you can't keep using keyboard shortcuts to access it (alt+2 breaks because it is no longer workspace 2, it becomes 11 or another number). I can move workspaces between monitors easily with alt+m and alt+shift+m.
The other feature is that windows snap instantly without any Mission Control animations. That is a big one that really irks me.
Those are the two features that I need most days and I find Yabai completely unusable because of the lack of workspace support
