Not everyone has access to a 6x4 table or model terrain. Also, model terrain can have issues where models can get nudged (or "nudged"), and you can end up in arguments about whether a model is in cover or not,l which won't happen with a hex grid.
By the way, I love that BOTH Hexed or Non-Hexed are being offered. I plan to use both, depending on the players I'm hanging out with.
My overall group runs the whole gambit: From "Gentleman's Honor" games where we know that accidental nudging is going to happen, (One our favorite games has a "shimmy" rule that lets pieces squeak by each other within reason) to hexed games that save us time (no analysis paralysis from the fear that a guessed shot was the wrong call before confirmed measurements.)
Probably one of the funnier moments in our group though, was from non-hexed game. A kid new to the game store saw us play and in his excitement picked up one of my pieces from the board and exclaimed. "This is so neat, what is it!"
"It's a game, based on placement," I said. And then I smiled.
We all had a good laugh and he became a solid regular until he had to move.
