APFS: This is the default file system in Macs with High Sierra. It is efficient and reliable. However, it won't be readable and usable on machines that are not running Mac High Sierra, Windows or Linux PCs. What's more, it is compatible with SSD and flash storage devices only.
Mac OS Extended (Journaled/HFS+): If you didn't update your Mac OS to High Sierra, the default file system on your Mac shoule be Mac OS Extended. Mac OS Extended (encrypted) would be an ideal option if you probably carry your laptop or external drive here and there. You can encrypt it so that no one can access the contents on your drive.
MS-DOS FAT (aka FAT32): In addition to Mac, it can also be written and read by Linux and Windows. It enables you to regularly share files with your friends. Nevertheless, this older file system is limited to no more than 4GB and there might be security issue and disk errors.

NTFS: As the default file system in Windows, it can only read by Mac OS and writing to it is not available. Luckily, there are third-party tools to help you do so.
