Fantasy Grounds has got a pretty face but there's not much brains behind that smile. I prefer kloodge.
Take the battle map: With FG, you placed a letter ball on the map to mark characters and monsters. With Kloodge, you have icons with pictures. In FG, the map knows nothing about distance. You have to use a map with a grid on it. In Kloodge, you can measure a distance on the map and tell kloodge how far that it. It can then scale the map for everything. It tells you how far you moved a figure, how far away an opponent is, and you can draw, say, a 20' fireball radius to see who it gets.
Or take attacks. With FG, you type a modifer into a box and then pick up the d20 and drop it to make an attack roll. And do that again for the second claw. And then change the modifier and do it again for the bite. And then do it all over again for the damage. It's going to take a long time.
With kloodge, you have a character sheet where you can enter the attacks. To make an attack it's one click. To roll damage, it's one click. Kloodge is also smart enough to do all of the math for you. Tell kloodge that you're raging, blessed, and bull strengthed; and it can make all of the adjustments for your attack and damage rolls on the fly.
