>>13445223>Would you say he covers the most important aspects though?Hard to say yes or no, because different people will consider different things important. But put it this way: If Person A tries learning the Calc I & Calc II curriculum through Lang's books, and if Person B tries learning the Calc I & Calc II curriculum through a meme book such as Stewart's, there will be questions in the curriculum that Person B will be able to solve mechanically while Person A will most likely stumble. This is particularly true with more applied problems.
