I really like this grammar. Futato's chapters are simple to follow and I don't find myself getting overwhelmed. I'm teaching myself and am not having difficulties. I wish Futato would break things down into patterns like Bill Mounce does with Greek in his beginning grammar; I find myself discovering the patterns myself to aid memorization (which has helped). By the way, the Logos version includes the corrections from the second and third printings which resolves one of the common complaints with this grammar in the past (reference https://www.eisenbrauns.com/assets/misc/Futato_Corrections.pdf).
