We looked into both when writing an open-source admin interface for NestJS. We went for bootstrap because:
- Nobody likes bootstrap, but everybody knows bootstrap (good for an open-source lib)
- Better browser compatibility
- Better accessibility
- Plenty of UI widgets built on top of bootstrap (we don't use them, but people using the lib could)
- About as big as each other
