A solid collection, like all the other editions. The sixth edition carries over some of the more timeless and stylistically obvious essays from previous editions with a handful of new narrative essays to keep the collection fresh.
My only complaint is, most of the new essays are narrative essays and yes, some of these essays can also be considered descriptive or example essays but focusing on essays that positions itself as a personal essay is very limiting in scope for what I'm trying to teach my students, forcing me to use more outdated essays or a repeat of last terms' essay selection -- which is boring for both the students and myself.
I wonder if this is due to the fact that analysis, argumentation, critical thinking are less important now than personal experience and so the reason for the lack of more critically thoughtful essays that ruminate and analysis is due to the hard shift to individualism and the individual experience. If so... :(
