Kickstarter asks the community to shoulder the risk of development -- you put your money in, with explicitly no guarantee that you'll get a game out of it (just a guarantee of a good-faith effort to put the game out), much less a good game.
As much as the big publisher model trends towards games that feel somewhat alike and tend to chase trends, it moves the burden of risk onto an entity that's designed to assume that risk.
Unless I'm missing something, Fig's model also asks the community to shoulder the risk. The only substantial difference is that with the Fig model the community also shares in all of the potential upside, whereas Kickstarter offloads the risk, but caps the maximum upside at getting the game you backed.
To be clear, fig also provides the Kickstarter model alongside its investor model. So you don't have to choose one platform over the other in terms of how you want to risk your money.
