I have. Maybe I don’t have enough RAM for it, but I find their IDEs to be slow and laggy.

Xcode and Visual Studio Code feel so much snappier on the same machine.

I find it very weird that Xcode is faster than... anything, really

It may be faster than.. visual studio.

It IS faster than JetBrains, at least on my machine.

Take some time to learn the navigation and refactoring abilities of the JetBrains family. It is IMHO unmatched by most. Using almost any other IDE feels like a downgrade, especially on large codebases with complex dependencies. Beyond Java, they have excellent support for Python, C#, Go, Javascript, and more. The engine builds a deep understanding of your code, which can make ctrl-space to suggest a method on an object feel delightful (and a Godsend on big Java names).

I also strongly prefer the keyboard shortcut set JetBrains uses. Having to reach all the way up to my function keys for combo operations makes me sad; even when I use other IDEs I love using an Intellij keybinding when available to quickly jump in and be efficient.

But to your point, I also tend to use it on higher end workstations (i.e. minimum of 16GB RAM, local repo pulls on fast SSDs, tons of logical cores, etc.).

Used JetBrains for more than 10 years, but got tired of it lagging all the time and using so much memory (even on M1 Pro with 32GB RAM, even on small projects). So I switched to VSCode for everything except Java. And I’m not a person who is easily annoyed I would say.

They seem to have fixed a lot of the weird lags recently. Right click context menu used to be slow, and the python debugger had performance issues for sure up to a year or so ago. Both way better now

I used VSCode for JS for a while, until a major refactor, the experience was awful and I switched to Intellij. I love it and never going back.

They limit the usable memory way too low by default — if you have RAM increase it to at least 2GB, but 4 may be even better and it will be snappy as hell.
