ANSWER:

The hadeeth is not authentic according to a lot of scholars. Even if it was authentic, it refers to rewards in some aspects but not in who is better or best among the people as there is no comparison between the companions and others at all. 

Sheikh is the hadeeth authentic that if we follow Islam during the ends times we will will be like 50 companions of the Holy Prophets SAWW. Pls elaborate this hadeeth further!
