Yes, we are fortunate to have many “legitimate” gadolei torah and other chashuva rabbonim who are certainly big tzadikim and talmedei chachamim and are sometimes also referred to as “gadolim” but probably in a second or third tier. Many of their followers may regard them as “gadolim” but the last time I checked, there is no official certifying body for gadolim. There are a small number of gadolim who are so regarded by just about every frum yid, but if you asked the CR readers here to a “top 10” list, I suspect there would only be 4 or 5 names who would be on everyone’s list.
