Personally, I feel that Cyrillic alphabet looks more beautiful than Latin or Greek alphabet, although Cyrillic letters mainly derived from the letters of Byzantine Greek. But even so, it would be very difficult, for those who're familiar with Latin alphabet, to learn a brand new writing system, such as Russian Cyrillic. Perhaps Cyrillic isn't much easier than Arabic letters for those beginners who don't know either Russian or Arabic, and most of all, the grammar of Russian is even more complicated than German, and maybe not easier than Arabic in many respects.
