Core utils is something like GNU, which are basic commands like ls, echo, cat, etc.

# Comparison of echo implementations

• GNU is bloated
• Busybox is a little bit less bloated, but still bloated
• OpenBSD nice
• Plan9port nice
• sbase nice

Just choose which fits your use-case best.

Shells mostly use their own echo (1) implementation and not the binary.
