Roger Waters and David Gilmour earned co-writing credits – and traded vocals – on Pink Floyd's "Comfortably Numb." So it only makes sense that they'd both make the song a signature part of their solo sets. But who played it best?

Gilmour recently returned to this fan favorite from 1979's The Wall, with actor Benedict Cumberbatch taking over for Waters on the verse. Water, meanwhile, played "Comfortably Numb" as part of his two-weekend stand at Desert Trip. Check out fan-shot video of each rendition below, then tell us who came out on top.

In the time since Waters split with Pink Floyd in 1985, multiple singers have replaced him as vocalist on the verses during Gilmour's solo shows – including late Pink Floyd co-founder Richard Wright, David Bowie and Bob Geldof, who had portrayed "Pink" in the film version of The Wall, among others.

Meanwhile, Waters' solo versions have found Van Morrison (at the 1990 concert immortalized as The Wall: Live in Berlin), Bruce Hornsby, Don Henley and Eddie Vedder (during the 12-12-12 concert for Sandy Relief) replacing Gilmour. Dave Kilminster and Snowy White, a former member of Thin Lizzy, have taken on Gilmour's guitar parts.

"Comfortably Numb" has also provided moments of reconciliation. It was the final song performed by the briefly reunited four-man Pink Floyd lineup for 2005's Live 8, and the occasion for a rare collaboration with Gilmour during a 2011 concert by Waters at London's O2 Arena.
