"Stone Sour" received generally positive reviews. Most reviewers offered some comparison to that of vocalist Taylor and guitarist Root's other band Slipknot. While reviewing the album, Don Kaye wrote that "it's rare that a musician offers up another venue for their talents that proves to be equal to their fulltime outfit," stating that Stone Sour is one such case. While Rowan Shaeffer of "Counterculture" states that "Get Inside" is "the closest to Slipknot that Stone Sour get," even comparing it to the Slipknot single "Left Behind". Citing "the chugging rhythm, manic kick-drums and shout-along vocals" as specific elements that are reminiscent of Slipknot, adding that it was "an obvious choice for a single" as it would not alienate their potential audience of Slipknot fans. Jason D. Taylor noted the similarity in lyrical content to that of Slipknot's; however, he stated that vocalist Taylor comes across as less infuriated which "allows the songs themselves to settle smoothly, yet motivate the listener to feel the emotion". "NY Rock" stated that the album has a "more balanced feel to it" than that of Slipknot's most recent release at that time, "Iowa".
