The Japanese and English portrayals of Spike have also drawn praise individually. While praising the Japanese cast as "perfectly complementing the characters", Kenneth Lee of EX.org argued that "there could be no one else to fill the role of Spike Spiegel except Yamadera". Meanwhile, IGN's Ramsey Isler stated that "Steve Blum launched his career into new heights when he gave the performance of a lifetime in the English dub of the series, giving Spike a sense of smooth, effortless cool that many argue surpassed the original Japanese version." Commending the principal American cast's work as one of the best English dubs, Serdar Yegulalp of About.com highlighted Blum as Spike as the standout performance of the series, stating that "Cynicism never sounded this suave or self-assured". However, AnimeNation's John Oppliger felt Spike's character was mishandled in the English dub, where he was depicted as a "carefree playboy" whose ambivalent taunts "come across as casual off-the-cuff bluffs, unlike his weighty, solemn statements in the Japanese version". Blum himself has called Spike a "gigantic benchmark" in his career and life, saying that "Spike changed everything" for him. He stated that his role as Spike opened up new opportunities for voicing characters, including T.O.M. on Toonami and Jamie on "Megas XLR".
