Beatles Remasters: Mono vs. Stereo Debate Thread

On September 9th, the entire Beatles catalog will be released in both mono and stereo remastered versions.

The issue of this thread is simply mono or stereo, and why? I only have the stereo CD versions that were available in the mid to late 1990s. I am too young to remember the original releases.

Until the albums are released, I'd like to get your take on the issue based on what has been on the market up to this point. After they are released, I'd like to hear from people who purchase either the stereo, mono, or both of the new reissues.

What are the pros and cons of the different mixes? Which do you plan on purchasing, if any? Discuss.
