I hate Hexes. I know I'm in a minority on this.
Consider this: It takes just as many turns to take the red path as the white path. The closest distance between two points should be a straight line. With Hexes, that's not necessarily the case.
I know squares have their own issues too but that particular issue with hexes always drives me crazy.
There are certainly some tactical benefits to hexes and the debate between hexes and square tiles will continue unabated but I don't like them personally.
And yes, to repeat, I know most people disagree with me. It's a personal preference.
