Glad you asked; there are several key differences between the editions!
The Box Suite edition is printed on a thick, premium cardstock: the monthly artwork side is coated and glossy to best complement the art, while the date grids are uncoated and matte for maximum writability. The monthly artwork features perforations on the top and bottom sides, so that after the end of the month, your spread becomes a fine art print. Each print can be removed (without any trace of either the drill hole at the top or the wire binding at the bottom), framed, and displayed on the wall as a permanent piece of art. This is the edition for the sports fans who also see the appeal in getting twelve original, sports-themed art prints out of their wall calendar at the end of the year (or framing as they go!).
The General Admission edition is printed entirely on matte paper (100#, which is a standard weight for wall calendars) with maximum writability in mind. The monthly artwork is not perforated. This is the edition for the sports fans here for the thrill of reliving legendary moments in sports history, but not concerned with saving the original artwork after the month ends.
The General Admission edition is saddle stitched (or staple bound) while the Box Suite edition is wire-o bound (this hangs flat, which is important for your art-prints-to-be). Both editions feature a drill hole for easy wall hanging.
