Surprisingly, I enjoyed both of them. They are actually very different books and both enjoyable for different reasons. And anyone who has ever been a breastfeeding mother (or who has attempted to breastfeed with little success) will love Fey's chapter on attempting to breastfeed her child.
Both books are well written and both deal with people who don't come from a traditional show-biz background but who made their way into success, ultimately both ending up with NBC sitcoms - Fey with 30 Rock and Lowe on Parks and Recreation.
Of course both authors are the stars in their own stories so to speak, so if you don't like (or are not prepared to like) either Fey or Lowe you may not like their books.
One little thing bothered me while reading Lowe's book, though. He refers to a number of his apparently well-known movies and I have no recollection of seeing or hearing of any of them other than St Elmo's Fire and About Last Night. I had never even heard of The Outsiders - neither the book nor the movie. I grew up in Australia and wondered if it was possible that none of these movies ever made it to distribution there. I checked with another Aussie friend who had also never heard of most of his movies. Do others from different countries have similar "gaps" in their "Brat Pack knowledge"? Or was I just a bookish young girl who didn't care much for the teen scene??
