Amateur mind or reassess your chess

Are these books the same material mostly but with different titles or are they truly different. Debating on getting both but don't want to waste money if I essentially brought the same book. I wouldn't mind if one has different positions to work with tho.

I have both, and there are differences. Amateur's mind is more like a workbook. Reassess feels a lot more theoretical. I got Reassess first, but after getting Amateur's, I wish I would have gotten that one first.

Ok thanks
