A comparison was made before inadvertantly between the Lubavicher Rebbe and Rav Elyshiv. They were different figures. Rav Elyshiv was a Posek not a leader (he had no Yeshiva and wrote no Sefarim) He was a someone to learn with. The Lubavicher Rebbe was more of a leader in the sense he led people to do things via speeches and deeds . Im not sure if I am being clear on the difference.
Maybe comparing Rav Elyshiv to Rav Kotler might make it easier to compare, there would be no Lakewood without Rav Kotler and in that sense Rav Kotler was closer to the Lubavicher Rebbe than Rav Elyshiv
