Yes
This is opinion, but it also has an element of fact to it.
You originally stated that in the US 1400 watt vacuums were common in the 1980's, and I only made comparisons to what we had in the UK in the 1980's. I WAS just stating my opinion and which one I believe is better. Give me a week and I will be able to prove my point, it's just I am away for a while, and evidence is at home whilst I am away from it.
How are metrics measured anyway?
