From 2016 to 2018 I worked on a complex case management application that was implemented in Smalltalk. It ran on Visual Smalltalk Enterprise (last updated in 1999! But the app was first put into production in 1996...) which is really quite crufty compared to Pharo, but the development experience still blew me away. The Smalltalk way of working takes some getting used to, but once I got into the swing of it, it was the the smoothest development process I've had: you log into the app and do your stuff. Poke some bugs, try to reproduce them, maybe find some completely unrelated error, and whenever you update the code you just save the methods and pick right back up from where you left off.
