Yeah, the Bible is considered divinely inspired, as in God inspired the human authors of the Bible to write it. It is the Word of God, but not the literal Word of God. The Quran, on the other hand, is considered to be literally Allah's own words, transcribed by Muhammad. The text of the Quran- every word of it- is taken by Muslims to be eternal and unable to be changed. It's to the point where a lot of Muslims believe that the Quran can only be truly understood if it's read in Arabic (in fact, Arabic is considered to be the holy language because it's what Allah spoke) and translations are only a pale imitation. Meanwhile, the Bible and its translations are taken less stringently because many Christians believe the spirit of the text is more important than the literal words.
That's the other major problem about Islam, Muhammad himself. Say what you will about Christianity, but even the most avowed atheists concede that Jesus himself was a cool dude with a lot of good messages. He was a pacifist who advocated that you should love and respect everybody, even your enemies. He promoted the image of God as a loving father who would always love you and forgive you for your faults. He condemned greed and hypocrisy, as well as people who use religion for their own personal agendas or to get power and money. In short, Jesus was an exemplary role model whose teachings are still relevant over 2,000 years later.
Meanwhile, Muhammad was... problematic, to say the least. I don't think he was a complete mustache-twirling villain who never did anything good, because there are some sayings and actions attributed to him that are good. But imo the bad things he did and said vastly outweigh the good. He was a warmonger who took and raped sex slaves and married a 6-year-old girl. He codified 7th century behaviors that should have been left in the past but are still considered legitimate by Muslims because the "perfect man" did them (the most heinous of these is the fact that even today, some Muslims consider child marriage to be Islamic and lawful because Muhammad married Aisha. Child marriage is even still legal in some countries like Yemen because of it).
