The question is: does it make sense to buy toothpaste with fluoride then or can I buy one without? Just because my kids don't like the peppermint ones and other flavours are most of the times without fluoride

Always buy flouride toothpaste.
Fluoridated toothpaste is more effective than drinking water. The fluoride works by direct contact with the enamel. Another reason it doesn't make sense to put it in drinking water.
Fluoride in the water is beneficial in the pre-eruptive phase (when teeth are still growing). Fluoride ingestion increases tooth resistence to cavities if the ingestion happened while they were growing.
This does mean that fluoride in water isn't really useful after you have all your permanent teeth though.

Depending on where you live, there is already enough naturally occurring fluoride in the well water that adding more doesn't mean much. How else do you think they discovered fluoride helps your teeth?
Since I live in a rural area and need to have my own well, I know my water contains enough fluoride that it would be silly to add more. But some areas do not have enough naturally present. So it would be interesting to see the water test results for Florida cities to check the amount of naturally occurring fluoride present. YMMV
Fluoridated water doesn't seem to make a difference on cavities. It does have neurological effects. It's simply not acutely fatal. It's already in our toothpaste. We don't need it in our municipal water supply and the majority of developed countries don't.
