Answer:
Both were reformers, but Ulrich Zwingli was a harder critic of catholic tradition than John Calvin.
Step-by-step explanation:
Ulrich Zwingly was defenitely against catholic tradition in any sense, in fact he objected the pope as the leader of christianity and considered catholic doctrines as something useless and not related to real devotion to God. He propose to break any relationship with catholic chruch. Unlike Ulrich, John Calvin was not as willing to break all bonds with Catholic sacraments as he thought some of them just needed reinterpretation according to his reforms. Meanwhile Ulrich was not interested on mixing religion with politics because he thought Any institution could not lead to salvation rather than individual faith, John Calvin was interested on creating a Cristian state for all the ones who, according to his reforms, are predestined to salvation. It impled a mix between religious and political goverment, something, as stated above, Ulrich Zwingli would oppose.
