What is the ultimate goal of Buddhism? Is it nirvana?

What is the ultimate goal of Buddhism? Why should a person practice Buddhism, what will it provide to him? Various religions have various goals. For example, the ultimate goal in Christianity is everlasting life in Heaven through faith in Jesus Christ, while in Islam the ultimate goal is Jannah (Paradise). In Hinduism the ultimate goal is moksha, which means becoming one with the Brahma after death. But what is the ultimate goal of Buddhism? Is it nirvana? If it's nirvana then it doesn't seem to be a very great goal. The goal to achieve nirvana is basically dying and never coming back, because Buddhism believes in rebirth and the cycle of samsara, which it believes is filled with sorrow and suffering. Hence to put an end to this constant cycle of sorrow and suffering one should try to achieve nirvana. Am I correct??
