This "Who's the Best" question relating to the print media has come up in the past, and it is interesting to read the responses.
I think each magazine has a little something to offer everyone: amateur players, pool fans, pro players, enthusiasts, vendors, and professional organizations. The pool media plays a very important role in today's pool world, and it is nice to be able to read a variety of articles.
To say one is better than the other is a difficult choice (IMO). Personally, since I'm a tournament globe trotter, I enjoy InsidePOOL's coverage of tournaments. Pool is the number-one game played by Americans, the majority being social shooters, not pros, not Hall of Famers, and not roadsters.
At every single major event I attend, InsidePOOL is there providing coverage. At the InsidePOOL vendor booth, there is an abundance of free and complimentary issues, available to all, which is a real nice bonus.
In addition to InsidePOOL and Billiards Digest, Pool & Billiards Magazine has some interesting articles as well. I've got quite a few older issues of P&B mag in my pool library.
The National Billiard News has been around since the '60s. I recently acquired every single issue from 1975 to 1985 to assist me in a project I am working on. These pool mags, especially the ones from yesteryear, are a godsend, and provide a detailed description of the sport's history.
How lucky we all are in this small subculture to be able have more than one in the way of reading material!
