Joint world record holder Asafa Powell and former Olympic champion Marion Jones won the men's and women's 100m at the Paris Golden League meeting.
Powell was not overly impressed by his dominant display in Paris
Jamaican Powell scorched to victory in 9.85 seconds, more than two-tenths of a second ahead of Marcus Brunson.
"It was just OK - I was hoping for something more," said Powell.
In the women's race Jones produced her best performance since 2002 as she powered home in 10.92 seconds, Jamaican Sherone Simpson came home second.
"To win with a field like this says a lot about my training so far this year," said Jones.
"Overall I feel pleased with the victory. There were some technical mis-steps in the race but a win is a win."
Jones - who has never failed a drugs test - has been the subject of doping allegations over the past couple of years.
She has not been invited to big European meetings since coming under scrutiny by US authorities in connection with the Balco doping affair which has rocked American sport.
"People that know me and have supported me know the truth," she insisted.
"All I can do is run races out here and people will make their own opinion on me.
"I love the sport and one or two accusations are not going to keep me away from it."
The meeting at the Stade de France saw five world best times for the year posted.
World and Olympic champion Jeremy Wariner closed in on his manager Michael Johnson's world record with an outstanding victory in the 400m.
The Olympic and World champion won by more than a second from Andrew Rock in a career-best time of 43.91 - Johnson's record stands at 43.18.
"It felt easy," said Wariner, who trains under Johnson's old coach Clyde Hart.
"With the way my training's been going, I can hopefully get down to the mid 43s by the end of this year. There may be a chance I can go 43.3."
Yuliya Chizhenko, the world indoor 1500m champion, held off the late charge of fellow Russian Yelena Soboleva to win the event in three minutes 55.68 seconds, the fastest performance in nearly three years.
World record holder Yelena Isinbayeva marked her outdoor seasonal debut by leaping 4.76m to win the pole vault.
Ethiopia's world record holder Kenenisa Bekele put last month's Golden League defeat in Oslo behind him with victory in the 5,000m in 12:51.32.
American Terrence Trammell won the 110m hurdles in 13.06 seconds.
Sanya Richards could not better her own world-leading time but the American was in a class of her own as she claimed the women's 400m in 49.73.
Ethiopians Tirunesh Dibaba and Meseret Defar played out a fascinating duel in the women's 5,000m.
Defar took the bell in front but Dibaba closed her down and just pipped her on the line in 14:54.24.
Dibaba, Powell, Wariner and Richards are the only athletes still in the hunt for a share of the $1m jackpot.
