Q. We have a debate in our new created minyan as to which is the most correct way to count Sefira. Most mentioned that the use the most common counting by saying Laomer. Yet we have a small group that recites Baomer, What is the correct thing to do?

A. Indeed Poskim disagree at what is the correct nusach or tradition to use. Many Rishonim quote “Laomer” (Beer Heitev 8, Sheloh, Pri Megodim in Eishel Avrohom 5, Shaarei Torah 8, etc.).
Others quote Baomer (Rema 1, Taz 3, Eliahu Rabba 7, Shulchan Aruch Horav 7, Chayei Adam 131, Hagr’a, Mharam Shik, Chazon Ish, see Nitei Gavriel 32: 5).

ArtScoll sidurim on nusach Ashkenaz maintain Baomer while on nusach Sefarad quote Laomer.

Horav Shlomo Miller’s Shlit’a opinion is that one you should follow the tradition of the majority of the attendants.
