The way to tell which ones are safe is to look up legal history for each company. When the home country of the company demands all the data they have, the companies are going to give all the data they have. So if a court order of a VPN yields nothing or almost nothing, then you know they really don’t save any logs.
As someone else mentioned already, proton and mullvad are the good ones in, but that can change if either company gets bought out or changes management etc
