To give you an idea about numbers. My mortgage is around 440k with a monthly payment of +/- 1500eu (includes interest). For the same apartment a 1500eu rent a month isn't unheard of. On top of this you have to pay for electricity and heating yourself and the insurance. When renting the additional tax (e.g. waste or sewer) is also added on top of the monthly payment regardless of buying or renting. The only thing that you have to pay when buying is when things break down, or the so called 'VvE' which is an organisation maintaining the building itself.
So yes I do agree with the statement that it cannot easily be compared, but in the situation of The Netherlands I feel like this is the right choice to make.
Edit: Although, if you (or anyone) disagrees with it I am curious to know why.
