全都 (quán dōu) is the everyday, neutral way to say 'all, without exception' — it's the go-to word for 'all' in most contexts. It's more colloquial than the formal 一律 (yī lǜ) and 皆 (jiē), and less emphatic than 统统 (tǒng tǒng) or 一概 (yī gài), which often imply a sweeping or categorical tone. Use 全都 when you simply mean 'every one of them' without extra nuance.
