This aptly titled disc features an urban music first -- a full-length collaboration between an R&B star (R. Kelly) and a rap star (Jay-Z). For fans who like their soul thugged-out and their hip-hop melodic, this is truly the best of both worlds. Tracy E. Hopkins
All Music Guide
Both R. Kelly and Jay-Z were flying high around the time of The Best of Both Worlds, so the idea of a collaborative album was a reasonable one, following up the success of The Blueprint (2001) and TP-2.com (2000). Unfortunately, Jay-Z's contributions (interjections and verses, mainly) sound like filler on The Best of Both Worlds, although Kelly fares better, supplying some potent hooks and co-producing the tracks with the Trackmasters (i.e., Poke and Tone), but he can't carry the album alone. Still, there are some moments where the collaborations click, particularly on the album's singles, "Get This Money" and "Take You Home with Me." Jason Birchmeier

The Best of Both Worlds is far from the musical epic these men are probably capable of making together, but it should quench (with a small twist of conscience) its audience's insatiable thirst for thug life. Kris Ex
