Guess its what you're used to. I actually find using hex maps less comfortable than not using them - but then I have 35 years of basically exclusively playing wargames that don't use hex maps (and I don't play board-games as such); even the RPG maps I play one are squared, rather than hexed[1].
That said, I have noted in the past there seems to be a discrete global divide in mindset - a lot more American sets of rules of my experience (e.g. BT, Silent Death) are hex-based than UK ones (e.g Full Thrust, and - much as I twitch to invoke it GW's rules). That may not be as true nowadsay of course, but it was fairly apparent twenty-plus years ago.
[1]Yes, you could argue that hexes are better overall for a gird if you're using one, but its bad enough trying to draw Paizo's sodding circuler and curved rooms and nearly-squar roomes-that-don't-quite-match-the-grid; trying to translate that to hexes at the same time would be a good way to send me INSANE.
