Once IntelliJ is running, which takes less than 10 seconds, projects open instantly. Probably even better on desktop machines.
Frankly VS code isn't good enough yet. It's the best if isn't for JetBrains but for instance, SQL queries are still just a string (unless I've missed the obvious plugin to allow me to auto complete column names and such according to the live database schema) but IntelliJ can highlight, auto complete and check errors once I register my database (also through ssh tunneling).
I do like VS code being faster but feature wise, I only use it to edit server config files through sftp plugin.
In 5 years, maybe JetBrains might feel pressured from competitors.
But it's only less than $15/mo if you pay annually and from 3rd year for their all products pack.
(This is mostly for Javascript: Typescript is more Java-like, so IntelliJ's tooling may be better there.)
What? MS made TS, VS code is written in TS but somehow when it comes to TS, VS code doesn't work as good as JS?
I'm sure someone else will benefit from this suggestion though. Intellij is pretty flexible and it is amazing what it can do, if you don't mind the performance trade-offs.
It feels less native than Electron apps.
I pay for Resharper every month. JetBrains makes excellent products. But I tried IntelliJ, I quickly went back to VSCode.
I really loved Intellij and I wish it could be made to run more efficient. VSCode fills the niche of "loads fast, moving around code is fast, and I can have many instances open at once without crushing my computer"
I guess it depends on the type of project you're working on, but I think these tools still serve separate use cases.
