I think Jim Clark along with Schumacher. I remember Senna talking about Schumacher's corning technique, very early on, Senna knew Schuey was something special early on. But Clark's career already was done and dusted to be talked about properly at the time. I wish Senna was alive to have commented on Schumacher's career after his retirement, I think Senna knew who were the best of the best, because he knew his limitations very well.
I was reading up on Jim Clark, and then found this article:

For what it is worth, I believe Jim Clark to be the Greatest Sporting Scot of All Time and to back up my case call upon the late Ayrton Senna who, shortly before his death, commissioned an oil painting by the Mexican artist Hugo Escobedo.
The canvas depicted Senna's ultimate 'fantasy' Grand Prix; an impression of the starting grid at Monaco featuring all of the greatest drivers in Formula One history.
Juan Fangio sits talking to mechanics at the wheel of his 1950 Alfa Romeo 158... alongside the Argentinian, Stirling Moss is seen climbing into the great hump-backed whale that was the Vanwall.... Jackie Stewart, all Sixties sideburns, pulls on his helmet in the cockpit of his Matra-Ford... Emerson Fittipaldi, the first of the great Brazilians, is there in an early McLaren... Niki Lauda in the classic Ferrari of '75... and Senna himself, of course, squeezed into the all-conquering McLaren-Honda with which he won the 1991 world driver's championship.
Senna made only two stipulations: a) there was to be no trace of Alain Prost, his bitter rival; and b) Escobedo could place the drivers in any formation he chose, providing Jim Clark filled pole position. "After all," said the Brazilian in a rare moment of modesty, "he was the best of the best".
Fangio and Moss worshipped him as a young god, while Soviet cosmonaut Yuri Gagarin said by way of introduction: "I suppose you will be in awe of me, just as I am in awe of you."
Thus in my opinion, Jim Clark and Schumi are the best of the best. Although even as a die hard Schumi fan, I think Jim Clark was like Schumacher of Scotland in dangerous times with the best tracks and hardly no safety, I give Jim Clark 10 out of 10 for that, and put Schumi at 9.9, simpy because Jim Clark did it first, like Sean Connery did Bond in the 60s

I would like to see that Fantasy Granx Prix painting Senna comissioned, wonder where it is.
