Which online program have you had success with

I'm looking to study Mandarin, but I'm not sure which program to purchase. I learned Tagalog (Filipino) to a fluency level, so I think a 3rd language will come quicker. I've looked into the Mandarin Blueprint, but it seems pretty pricey compared to many other online training programs such as ChineseforUS and Yoyo Chinese. Once I have a plan, I'm very studious and committed.. I plan on committing 2-3 hours a day to Mandarin. I'm just unsure which program seems to be the most useful and comprehensive. Thanks
