Really hard to differentiate for PostgreSQL usage, both are great options. The main difference is that TablePlus supports a lot of other databases. I slightly prefer how Postico does things, also it has better PostgreSQL support (TablePlus is good but not great with arrays, hstore etc). I think the only thing that puts TablePlus ahead for my usage is being able to filter columns when viewing a row. I have some tables with maybe 40-50 columns and many similar column names so browsing with Postico can be a bit tedious.
also interested in this. Anyone have experience with both?
Using both, both are very good. Sticking to postico most of the time due to better UX (totally IMO of course). Also, try v2 https://eggerapps.at/postico2/
