What was common in the reforms of Servius Tullius and Solon? How were they different?

The commonality of the reformism of Solon and Servius Tullius consisted in the orientation towards democratization – the involvement in the life of society and government of all classes – both the rich and the poor;
the abolition and limitation of debt slavery;
recognition of the nobility, aristocracy, not by kinship, but by property – the more there is, the more noble.
The difference between the reformism of Solon and Servius Tullius was in the degree of achievement of democracy. In Greece, with the National Assembly, courts in which all free citizens – demos, participated, the degree of democracy in society was higher than in Rome.
