Mtr is more useful than traceroute in some ways, it can display information about each hop route in real time, and constantly probe.

Traceroute uses UDP packet detection by default, while mtr uses ICMP packet detection by default. ICMP has a lower priority than other packets at some routing nodes, so the data obtained by the test may be lower than the actual situation.
