[pornel]

For a long time I had the same opinion (using Sublime Text with its plain same-file autocomplete). It's okay, but after using LSP for a while, I'm sold on it. It really is nicer, and I wouldn't go back to my pre-LSP times.

"Go to definition" and "Find references" is faster and more precise than grepping, especially for common function names. This lets me browse larger codebases, even if I don't remember their layout.

Being able to peek at actual types of variables is quite useful in Rust which has type inference. I can check types instead of deducing issues out of compile errors.

LSP support for like "Extract into function/module" are great for refactoring eliminating most of the busywork. Renames are also more reliable than find'n'replace, especially when I'm renaming because the name is ambiguous.
