Good fast IDE for reading and navigating code in multiple languages

With the use AI I find myself writing less and less code, but reading way more than before at work. I have been using IDEA, because in my experience no IDE offers code inspection and navigation as good as IDEA across multiple languages. But it's very slow and mostly geared towards refactoring and editing. I have used VScode and I found it lacking as it is also slow. Nvim is very close to what I want but it takes some getting used to. Which IDE do you use?
