Play Store is only the safest way to obtain apps solely distributed through the Play Store. It's safer to get other apps more directly from the developers considering how much malware there is on the Play Store. There are tons of apps impersonating other software on the Play Store. There are lots of useful open source apps for people focused on privacy and security not available through the Play Store too.
