There is no best method. You should try out what works best for YOU. For me, for example, the method recommended by LingQ of learning a language from the scratch with comprehensible input doesn’t work and only leads to unnecessary waste of time.
When I start learning a language, I do it with a conventional textbook with CD/mp3. Only when I know the language at least a little and, above all, have understood how the language actually works, I start using LingQ. Then LingQ is a great tool for expanding the vocabulary and training listening comprehension. I also take a break from LingQ every now and then and use other methods of learning languages during that time.
So try out different things and you’ll soon see what’s best for you personally.
