Emacs has no "plugins", it's all just Lisp code, all the way down. Big Ball of Mud architecture refined to a state of sublime elegance.
Can I put my cursor on a defun in Visual Studio Code, Eclipse, or IntelliJ, mash C-M-x, and immediately have that functionality available in my running editor session with all my work? I can in Emacs, and that capability has allowed me to smooth out the rough spots in many a workflow.
Lisp is not just an "implementation detail", it's central to what makes Emacs great. GNU Emacs is a running Lisp image, which you can extend and shape at will as you work on something else. A phenomenal tool.
