I guess it depends on your goals and the timeline you have. I did Dreaming Spanish pretty intensively (1-2hrs a day) for 10 months. My goal was to be able to understand native Spanish speakers and hopefully communicate back to them. I absolutely achieved my goal in that when I went to a place with native speakers I could at least get the gist of what they were saying almost always, even in somewhat complex situations. However, I was basically able to speak on the level of a toddler and had to rely on Google translate to get what I needed to say across.

If you want to speak the language faster, then there are certainly ways to do it that may work better, but you will have to do more translation work that is mentally taxing. In the long run, if your goal is fluency, I believe CI should be prioritized initially and then you can go in and learn grammar rules and such later (much like how you learn your native language through input for the first 5 years of life then you go to school and learn the rules there).
