The contrast between rival Ashes captains Michael Clarke and Alastair Cook appears stark.
At first, anyway.
One is a heavily-tattooed city lad with a love of bling and a curious history of being misunderstood by his teammates and much of the nation he represents.
His unquenched ambition has steered a two-decade journey to the top of the game while his image, or, rather brand, has been finessed with as much care and intent as his rigorous training and rehabilitation regimes.
Often fractious and fidgety at the start of an innings, later he appears to execute strokes almost beyond imagination - rarely brutal in the way of David Warner but measured and clinical in their precision.
He is a man of his time and, comfortably, the best player of it.
The other captain is the product of a Gloucestershire village and, mussed hair and all, still looks much like the choirboy he once was.
His batting appears a natural extension of himself - unruffled and even-tempered, it would be as much a shock for him to play a reverse sweep as it would for him to turn up for Test duty sporting a monstrous diamond earring or forearm tattoo.
The owner of a Bedfordshire farm, he is never more content than when getting his hands dirty with sheep and turkeys or joining his mates for an after-work pint at their local.
Polite, solicitous but possessing plenty of inner steel, it is difficult to imagine any teammate failing to provide him with the utmost respect.
"There is no other man I'd want leading us on to the outfield because he leads from the front and leads by example," wicket-keeper Matt Prior said on the eve of the Test.
Cook may not be the best player in his team, though he often comes close, but he is as reliable as his sheep dog and no less effective.
Clarke is the best player in his team and starting to develop a degree of effectiveness as captain.
The flashpoint at the Gabba, where he confronted James Anderson in an ugly but revealing moment of red-hot tension, may have signalled his growth from an individual mostly interested in image for one solely committed to matters of substance.
His strike weapon in Mitchell Johnson saw the difference.
"The past 12 months I've been really happy with his style of captaincy," Johnson said.
"He's been aggressive when he needed to be, pulled it back when he's needed to.
"He's just been really good on the field as a skipper. As we've seen through this Test series he's really stepped up when we've needed him to as well.
"Not necessarily just with that bat, too. What happened in Brisbane … I thought it was great what he did. He stood up for the players. That's what you want from a captain."
Clarke and Cook, two sides of different coins. Yet they compare as easily as they contrast. A series of historic and statistical parallels are by no means the least of their common ground.
Like Clarke, Cook travelled to India to make his debut and, like his opponent, he soon made the cricket world sit up and take notice of a rising star.
Clarke's first game was in Bangalore in 2004 and he marked it with a blazing 151 that was so imposing that teammate Darren Lehmann soon offered to stand down from the team to give the youngster nicknamed Pup an extended selection run.
There was no suggestion from any senior England players they would move aside when Cook made an unbeaten 104 on debut in Nagpur two years later, though it was noteworthy the left-hander has only missed one match since then - when illness laid him low on the eve of what would have been his third game on that India tour.
The most striking coincidence will come at the WACA Ground today when they both play their 100th Test matches.
Cook will be 28 years and 353 days, making him the youngest Test cricketer to the milestone.
Clarke is four years older, his career pitted with several early stutters before he became the rolled gold run-machine of the past few years, though only Ricky Ponting, Shane Warne and Steve Waugh beat him to the mark amongst all Australians.
Two, even three players, have previously reached the milestone in the same game.
England colleagues Mike Atherton and Alec Stewart both reached their centuries against the West Indies at Old Trafford in 2000, while South African duo Jacques Kallis and Shaun Pollock, as well as New Zealand opponent Stephen Fleming, got to 100 at Centurion in early 2006.
Clarke and Cook will hit the tape together today but they remain in keen competition to become the first to 8000 Test runs.
But their contest could be overshadowed by Kevin Pietersen, who made his 100th appearance in the first Test at the Gabba, and leads the race to 8000. Pietersen needs just 12 runs, while Clarke must score 60 and Cook 117.
Runs came easily to Clarke and Cook at the start of their careers while the responsibility of captaincy has heralded a golden run for both batsmen.
Yet Cook has started to appear mortal this series, with Australia closing down his favourite scoring areas to keep him to 20 runs an innings.
Just as he did in his three other Ashes campaigns, apart from the remarkable summer of 2010-11 when he constructed 766 runs at 127 to help defend the trophy, he has been a mediocre performer who averaged 27 in 2006-07, 24 in 2009 and 27 this winter.
Clarke has been more consistent in his productivity with averages of 37, 77, 64, 21, 47 and currently, 77, in Ashes series.
It will be a great moment for both players today when they reach 100 Test matches.
Unless matters turn around rapidly, there may be another parallel in place by the end of the week.
Cook won 3-0 in his first Ashes series as captain.
Clarke will be in his second series but all the signs are pointing towards a 3-0 Ashes win by this time next week.
