What are the differences between Western and Eastern Slavs?

The Western Slavs today include Poles (including ethnic groups of Kashubians, Kabats, Silesians), Czechs (including Moravans), Slovaks and Lusatian Serbs, and Eastern Russians, Ukrainians and Belarusians.

The differences are:
The Western Slavs had statehood earlier, for example. among the Czechs in the middle of the 7th century, and continuous from the beginning of the 9th century. From the second half of the 9th century among the Eastern Slavs.
Western Slavs in the middle of the century were Catholics, and then partially became Protestants. Eastern, on the contrary, Orthodox or Uniates (in Ukraine and Belarus since the end of the 17th century).
The Western Slavs have a writing based on the Latin alphabet, the Eastern ones based on the Cyrillic alphabet.
The Western Slavs had previously eradicated illiteracy, printing houses appeared (15th century) and universities (14th century).
Statehood among the Western Slavs sometimes disappeared or is simply very young (Slovakia), among the Eastern ones it has been continuous since the turn of the 9th-10th centuries, although there was a period of feudal fragmentation in Russia (1136 until the second half of the 15th century).
