I'm an English speaker with some Spanish education and practice. My experience is that reading, writing, listening, and speaking can be quite uneven. Uneven enough to matter.
In the long-run, yes, learning a language is better, assuming your goal is to learn the language. I'm not trying to be snarky: sometimes people simply want to communicate an idea quickly in the short-run and/or don't prioritize deepening a language skill.
I would rephrase the comment above as a question: "Given the set of tools available (in person tutoring, online tutoring, AI-tooling, etc) and what we know about learning from cognitive science, for a given budget and time investment, what combination of techniques work better and worse for deepening various language skills?"
