PhD offer at high ranking university vs lower ranking one

So I am applying for PhD positions in Europe. I currently have two offers, one of which is from a big university and well-established professor but I am not really that eager about the topic and the supervisor is really good academically but he came off kinda cold and distant in person.

The other one is from a smaller uni (Qs~1000), but I am satisfied with the topic and the pi is really good both academically and on a personal level.

Of course I would be more comfortable working with the second option, but also I am trying to make the best decision long-term wise.

What do you think matters more? Ranking vs. topic and supervision
