I used Duolingo for about 6 months and learned very little. The gaming part over powers the learning part. It's too easy to guess and move forward without learning anything. Plus what you learn is very random to the point of being useless. It's way over rated.

I also tried Rosetta stone. It's a good companion to an other learning tool but not very good on its own.

I'm a fan of pimsleur language learning. It's old school but it works, if you do it consistently and follow what they ask you to do.

I think it depends what your goal with Duolingo is. I've had great luck using the app as smart flashcards, less so an end-to-end language learning solution.

Also a fan of Pimsleur. It’s a bit slower than other platforms but you will absolutely remember what you’ve learned, unlike most of the newer tools.
