Looks nice. Two main differences:
- BUSL is OSI-approved and listed in SPDX, so corporate lawyers won't be scared away by it: https://spdx.org/licenses/BUSL-1.1.html
- With BUSL the restriction is revenue-based. You can still create competing products, but would have to pay a licensing fee.
Good points, the second is very "dual-licensing" in nature. BUSL is certainly the more "mature" option and there's a higher likelihood people came across it in the wild.
