Memoirs, like any other genre, have examples I like, and others I don't. A lot of memoirs are plagued by a lack of self-awareness, or attempts by the writer to present themselves exclusively in a positive light. Of the books you read, I only read "Educated", and I know Westover was criticized by family members. I'm not a fan of celebrity memoirs (or most political memoirs, for that matter), as they tend to be self-serving and narcissistic. I can't imagine ever reading Jennette McCurdy or Tom Felton's. One exception from a celebrity was Trevor Noah's "Born a Crime", but he had a genuinely interesting life, and he's funny. Other memoirs I enjoyed in no particular order ... Lit, by Mary Karr; Memorial Drive: A Daughter's Memoir, by Natasha Trethewey; and Lab Girl, by Hope Jahren. Robin Wall Kimmerer's "Braiding Sweetgrass is a mix of memoir and nature writing, and is one of the best books I"ve read in years.

There are a lot of excellent biographies. Ron Chernow has written a few excellent ones about important people in US history. "Hamilton" is perhaps his most famous. David McCullough wrote an excellent biography of John Adams. Walter Isaacson's biographies are uniformly excellent. His biographies of Leonardo Da Vinci and Einstein ware particularly good.
