I think telecom broadband is faster and mobile broadband is cheaper.
First, mobile broadband
It is characterized by low price, being a second-class operator, delayed response time, and acceptable overall download speed, but unstable, easily disconnected and limited upload speed, which is suitable for users who only watch movies and TV series.
Second, Unicom broadband.
It is characterized by average price, good quality, instability and sometimes disconnection, and its application scope is medium.
Third, telecom broadband.
It is characterized by a large number of servers and fast response. The disadvantage is that it is a bit expensive and suitable for gamers.
