Jockey Barry Geraghty believes Sprinter Sacre's flamboyance makes him an entirely different proposition to the legendary Moscow Flyer.
The Nicky Henderson-trained six-year-old preserved his unbeaten record over fences at Newbury on Friday when breaking the course record in the Game Spirit Chase.
He is now the short-priced favourite for the Racing Post Arkle Trophy at the Cheltenham Festival.
Geraghty won the Arkle in 2002 aboard Moscow Flyer, considered one of the finest two-mile chasers to have graced a racecourse, yet feels Sprinter Sacre has a sharper turn of foot to that of Jessica Harrington's great gelding.
He said: "Call him (Sprinter Sacre) what you like - the business, the real deal - all I know is that he's special and I've never ridden one like him.
"Moscow Flyer was brilliant but he'd doss in front and would beat a bad horse by two lengths the same as a good one.
"You'd call him unassuming in human terms, but this horse is flamboyant.
"Nine times out of 10 Moscow was a good jumper, but Sprinter Sacre is fast - I've never ridden a horse that can get from one side of a fence to the other like he does.
"In fairness to him, he was clever at a couple, which a horse needs to be at Cheltenham - concentrate on the job.
"He was breathtaking all right, and he's the sort of horse that jockeys wait for their whole career.
"He just needs wrapping up in cotton wool and looking after as he's still got so much potential."
Geraghty shared similar thoughts about Burton Port, who made a superb return from a lengthy absence when second to stablemate Long Run in the Denman Betfair Chase.
The Irish-based rider is confident there will be more to come from the eight-year-old gelding when he lines up in the Gold Cup at the Cheltenham Festival.
Geraghty said on his At The Races blog: "He confirmed everything I thought after his good work a few weeks back and made Long Run go all the way to the line.
"He's third favourite for the Gold Cup now and I'd like to think the run would have bought him on a good bit.
"It's now a matter for the mechanics at Seven Barrows to keep the wheels in place for Cheltenham."
