All Blacks legends Dan Carter and Richie McCaw have played in some of rugby's most famous stadiums, but few players are better placed to judge which ground deserves top spot.
Between them, the New Zealand icons won four Rugby World Cup winners' medals and helped build one of the most dominant international sides in history.
Carter remains one of the greatest fly-halves to play the game, while McCaw captained the All Blacks to back-to-back World Cup triumphs in 2011 and 2015.
Both experienced the pressure of playing in front of enormous crowds, from the cauldron of Twickenham to the famous stands of Eden Park.
But when it comes to choosing rugby's greatest stadium, the two legends reportedly share the same opinion.
Cardiff gets the nod
The stadium in question is Cardiff's Principality Stadium, formerly known as the Millennium Stadium.
Speaking during the 2015 Rugby World Cup, Carter told World Rugby that Cardiff was his favourite place to play.
“I always say the Millennium,” he explained.
The former fly-half praised the atmosphere and the passion of Welsh supporters, comparing their love of rugby to that of New Zealand fans.
He also admitted the retractable roof was a bonus for kickers, keeping Cardiff's notoriously unpredictable weather out of the equation.

Richie McCaw shares the love
McCaw's admiration is perhaps even more surprising.
The former All Blacks captain endured one of his darkest rugby days in Cardiff, when France stunned New Zealand 20-18 in the 2007 World Cup quarter-finals.
Yet that painful memory did little to dampen his affection for the Welsh capital.
Speaking ahead of a return to Cardiff in 2009, McCaw described the Millennium Stadium as “one of my favourite places to play rugby”.
He particularly enjoyed the noise generated when the roof was closed, even if it made communicating with teammates difficult.
For two men who conquered the rugby world, that's quite an endorsement.
Eden Park might be New Zealand's fortress, but Cardiff clearly left its mark on both legends.
And when more than 70,000 Welsh supporters find their voice beneath that famous roof, it's not difficult to understand why.
