As a reference, since there are people saying that "Wii U sold well at launch too, so it's better to wait and see"...while the latter is certainly a good advice, and we'll have to see how the platform performs in the next few months outside of launch, the former is not true, at least in Europe.
Not only we have datas right in the OP showing how Switch had a debut 5x Wii U's in Spain, but there are also these numbers back from 2012

Out of 900,000 Wii U shipped in "Others", only 430,000 were sold between the European launch (November 30th, 2012) and the end of 2012. Remember: Zelda alone is over 325,000 copies sold in the first weekend at least (since 325,000 is the amount of Wiis sold in Europe in its first weekend).
Another reference - in its first weekend, 3DS sold around 303,000 in Europe.
