Was Fulgencio Batista a good Ruler for Cuba?

Answer:

Fulgencio Batista rose to power in a coup, and cultivated the friendship of Meyer Lansky, a mobster from America. Under him, the ownership of land in Cuba shifted to non-Cubans, particularly Lansky's "friends" in the casino business. Most of the farm land was under the control of American corporations interested in cheap sugar. Batista was corrupt and corporate greed fed that corruption.

So, at least in my opinion, the answer is no. Batista was not a good ruler for Cuba.
