Question: What are the most common compliments types received by user with uber number of fans?
Evidence: the most common compliments types refer to MAX(COUNT(compliment_id)); user_fans = 'uber';

SQL:
SELECT DISTINCT T3.compliment_type FROM Users AS T1 INNER JOIN Users_Compliments AS T2 ON T1.user_id = T2.user_id INNER JOIN Compliments AS T3 ON T2.compliment_id = T3.compliment_id WHERE T1.user_fans = 'Uber'
