Today it's not nearly as bad as it was before. I personally have very few reasons to use jQuery. Maybe it's somewhat shorter code and supports some cool pseudoselectors (IMHO, they are often bad patterns) but for me it's often easier to understand and debug a code using vanilla JS. For example, sometimes I have struggled to find the exact event listener callback by using dev tools because when you use nested click events because the code passes throw a lot of jQuery code before reaching the actual event listener.
