Jerry Hall's departure from Strictly on October 21 wowed 9.39 million (a 36.6% share) on BBC One, while an average of 9.33m (34.7%) watched Louis Walsh's group MK1 leave The X Factor on ITV.
Roughly, Strictly peaked with just over 10m in its 7.30pm to 8pm slot, while The X Factor reached a high of nearly 11m for its climax, and added 300k (1.1%) on ITV1 +1. The Xtra Factor followed with 915k (3.4%) on ITV2 (+1: 151k/0.8%).
This means Strictly has done the double over X Factor this weekend, after retaining a lead over its rival on Saturday.
But the night belonged to Downton Abbey, which rallied from its previous (October 1) high to a huge 9.69m (36.6%) in the 9pm hour. ITV1 +1 attracted 365k (2.1%) more Downton viewers at 10pm.
Meanwhile, the return of Surprise, Surprise to the ITV schedules after 11 years off, with Holly Willoughby replacing Cilla Black as the host, dazzled 4.28m (17.4%) in the 7pm junction.
Although slightly below the channel's usual slot average, Surprise, Surprise actually built more viewers as the hour went on even though it clashed with Strictly for the latter half of its slot, finishing its transmission with a peak of over 4.5m.
Over on BBC One, Countryfile climbed to a colossal 6.94m (32%) at 6.30pm, while Antiques Roadshow maintained a steady 5.62m (20.9%) at 8pm, and Andrew Marr's History of the World interested 2.33m (8.7%) an hour after that.
Elsewhere at 9pm, Dragons' Den rose to 2.1m (7.9%) on BBC Two, Homeland drew 1.86m (7.1%) for Channel 4 (+1: 360k/2.1%), and film The Book of Eli attracted 1.45m (6.9%) for Channel 5 (+1: 176k/1.4%).
Overall, ITV1 strolled to victory in primetime with 27.3% (+1: 1.1%), comfortably ahead of BBC One's 20.8%. BBC Two earned third place with 5.7%, edging Channel 4's 5.3% (+1: 1.3%), and Channel 5's 5% (+1: 0.4%).
