The best part is the host part
You have a nice interface where you can manage a tournament super easily
List of players where you can see / edit ther status like if they're in game / dead /lynched, edit their role / actions
Processing actions is also easy cuz since players use the tool to submit them you have all of them in one place so you can just open the list add a result, and once you've finished click save and all the players on the tournament will be notified of the result of their action so you don't have to go through each PM maybe missing someone or i don't want to imagine how is to manage all of this stuff with an excell xD
And you can also easily start new phases maybe put a vote limit to the vote count so when someone reaches a certain cap it blocks automatically ( though this is still in beta )
You can possibly manage multiple medium sized tournaments at the same time with just a couple of clicks
