Today I generally think of an IDE supporting one language (or a few complementary languages) without any configuration, whereas a text editor usually requires configuration to get the same features. Although it's true the features are almost identical now. Though IDEs typically still offer some special sauce features, usually things that still don't fit cleanly into LSP and DAP (language server and debugger protocols respectively) models. On the flip side, text editors typically (lightly) support more file formats out of the box, and scale better, e.g., equally comfortable editing a single file or an entire project. TLDR: the trade off is between flexibility (text editor) or specificity (IDE).
