I don’t know who the best is… but I went to a Ishay Ribo concert a few years ago… and his fans span the spectrum- Charedi, Yeshivish, Dati Leumi, secular… and to see everyone singing together with him אשרי העם שככה לו, אשרי העם שה’ אלוקיו was one of the most powerful experiences of my life, and something that I don’t think any other Jewish singer can pull off.
