Duolingo Is Not a Long Term Solution

The best method is the one that you do daily, they will take you to fluency. Definitely, especially if you have refold to guide you. We had a client come to us who had a multi year long Duolingo streak and was not anywhere near where you would think he would be after several years of study. It does like frustrate me a little bit because I think the people at Duolingo must know that it's not a long term solution.
