I've been using JetBrains IDEs for the last 11 years. Before that I used Emacs and Sublime Text. I've tried VSCode, Zed, and others. There's just no comparison on the code insights and code manipulation tools. LSP is far behind what JetBrains can do, although it's slowly catching up these days. I still use VSCode from time to time for other languages like Zig.
I've never experienced sluggishness, but, I also keep track of how much memory it's using and ensure I don't run low. It's clearly a huge resource hog, but I'm also glad for that. It's using all of my computers resources to analyze the code in amazing ways which help me develop fast. Emacs, Sublime Text, and others were all about typing speed. Fast development goes far beyond just typing speed.
