I use Map Tool, its free and excellent. There are Gurps frameworks for Map Tool, but I don't use them. Gurps has so many options it is hard to imagine a framwork that implements all the options used in any but the simplest Gurps Lite game. Anyway I prefer people to learn the rules, so beyond a button to roll 3d6 and some state symbols I don't use built in Gurps rules.

However I have a hex grid, facing and vision (Peripheral Vision, No Peripheral Vision, Darkvision etc. are all represented by the system).

I haven't tried Fantasy Grounds but don't pay for any Virtual Table Top until you've tried Map Tool.
