Hi, after having watched it, it makes it clear right at the start that this is not meant to be a review of 'which is best' but a summary to enable the viewer to decide which car is best for them. Nothing that we don't already know, in summary:
Seat: the smallest and cheapest, best for town driving due to size, a little bit dated and basic inside. The firmest ride of all. Options mainly available in packages rather than individually.
VW: Medium in size (of these 3), lots of individual options, driving set up to please the masses, not too firm nor too soft
Skoda: largest and most expensive, most modern interior, less options than VW, set up for softer, more comfortable ride (without DCC)
The review then ends in saying basically: now we have summarised for you, it's time to decide which suits you best. At no point does it state whether one is better than the other
