Sorry for the late response, missed this somehow. I'm realizing as I try to write this that it is a bunch of small things, and maybe it boils down to having used it a long time or it being my first non-garbage (SSMS, PGAdmin) UX db tool. The autocomplete seems to work exactly as I'm expecting, the filtering seems to work a little better than TablePlus. Copying and pasting is a bit more consistent (I do this a lot while dev'ing). The whole UI is lightning fast and always stays responsive.

That all being said, TablePlus is 80 - 90% of that and the fact that it also works with multiple databases is huge. I also love the vertical tabs for multiple connections, editor sidebar pane for single records and tabbed queries vs a single query pane.

Both are fantastic, but if I was postgres only I'd probably stick with postico. As-is I just paid for both.
