I concur. You really can't go wrong with either, but postfix has made some significant progress over the years. It used to be that if you wanted to do anything fancy, you had to use sendmail (or later exim) and the configuration was terribly hard. MTAs are one of those things that are constantly changing though, and postfix has grown up a lot since the grand-parent last seriously evaluated it.
Today postfix has excellent virtual user support and supports just about every authentication mechanism you would want. As for the article itself, the writer mentions that postfix docs are "scattered" around. I can't say that I've ever had a problem finding documentation for postfix, and what I do find is hands-down some of the best documentation I've ever seen for free software. The man pages are excellent (every bit as good as you would expect from the BSD world) and the txt and html docs included with the source code will walk you through just about everything.
For good dead trees documentation and an overview of how to do things with postfix, I found the O'Reilly book "Postfix - The Definitive Guide" by Kyle D. Dent to be excellent.
