Vishnu and Shiva come in great …

The terms great and little traditions were coined by a sociologist named Robert Redfield in the 12th century to describe the cultural practices of peasants societies. He found that peasants observed rituals and customs that emanated from dominant social categories, including priest's and rules. These he classified as part of a great tradition. These he included within the category of little tradition. He also noticed that' both great and little traditions changed over time, through a process of interaction. While scholars accept the significance of these categories and process, they are often uncomfortable with the hierarchy suggested By the terms great and little. The use of quotation marks for great and little is one way of indicating this.

They both came from great tradition because in South india, virupaksha temple was build in the form of shiva and vitthala temple was built In the form of vishnu.
