My Myriad of Marathons

Somehow I have 5 Marathons, but that's ok. They're tough and quality made watches. Two of these are the 34mm GPQ, General Purpose Quartz, one with Tritium, the other with Maraglo. I also have a GPM, officer's watch in steel. Plus of course the SSNAV, the Stainless Steel Navigator, and an Arctic TSAR. All fantastic! Which is best?
