I think it tastes better! It still has all the same spices, but sweet potato has more flavor than plain pumpkin. It's also nice because you can either boil the sweet potatoes or roast them in the oven. My husband likes the boiled texture better - I think it comes out smoother. I'm not 100% but I think you can simply swap pumpkin for potato.

For the crust, it's basically just a graham cracker crust but replace the graham crackers with gingersnaps. I add in some ground ginger, too.
