Difference between czech and russian language

Which is easier to learn Czech or Russian?
Russian uses Cyrillic alphabet, but it should be easier to learn it (and more practical to know it) compared with the Czech language.
Lot of people wrote that Czech is more difficult than Russian, but I would say that they are both very difficult for foreigners, especially non - Slavic..
The East Slavic branch comprises Russian, Belarusian, and Ukrainian (formerly called Ruthenian).
Of these, Russian is by far the most widely used.
It is the native language of Russia and the first language for more than 160 million speakers.

What is the difference between Russian and other languages?

Russian, as you know, has no articles, while in other languages, they usually take the form of stand-alone words

Whereas here, the article is attached to the ending of a word

For example, вълк – вълкът, м?

м? – м? м? т? , дядо – дядото, etc
