For those of you who self studied... What did you use?

Hello everyone...pretty simple question. I am interested in doing
self-study for my ground school. I feel like I would do better at my own
pace, and I have a lot of experience working with industry certifications at
home, so I don't think I will lose any quality training.

I have read about many different companies that sell self-study packages. I
have received paperwork from Sporty, King, and some other one's via email.
Does anyone have any comments on the different packages? Anyone want to
recommend one over the other, or are they all just about the same? Any
specific packages you would suggest, maybe comeplete with practice tests and
such?

Thanks from a new Student Pilot!
