Is it better to perform ablution at the mosque or at home?

Ablution at home is better than ablution at the mosque, due to what Muslim narrated from Abu Hurairah that the Prophet, peace and blessings be upon him, said: "Whoever purifies himself in his house, then walks to one of the houses of Allah to perform an obligatory prayer from the obligations of Allah, one of his steps will erase a sin and the other will raise his rank."
