I looked up this expression on teanglann.ie at got a bunch of results, all of which seem pretty good to me. Ó Dónaill gave i dtul, aghaidh ar aghaidh, béal ar bhéal, gnúis le gnúis, and eineach in ionchaibh. De Bhaldraithe had dhá dhream a thabhairt i láthair a chéile for 'to bring to parties face to face', but I think this one might not be as universal. Which ones do you guys know that are attested in native works?

Soir gaċ síar, fé ḋeireaḋ thíar

aghaidh ar aghaidh le duine

An t-éitheach a thabhairt do dhuine suas lena bhéal, to lie to someone’s face, lie to someone brazenly; or flatly contradict someone face to face, refute what he has said.

Thank you

While i dtul and eineach in ionchaibh may not be as frequently encountered, they can still be seen in specific dialects or poetic uses. The phrase dhá dhream a thabhairt i láthair a chéile is more formal and may appear in legal or academic contexts rather than everyday usage. Overall, the first three are your best bets for universality!
