Good for what?  MQTT is an unremarkable wire protocol, and is not particularly great at anything. It bandwagoned onto IoT and was never designed for it unless you define “IoT” very, very narrowly.

The major weakness of MQTT is its reliance on TCP for a ton of functionality. Relying on TCP for your networking functionality is a bit like relying on POSIX for I/O; it works sufficiently well for common cases that the problems can be overlooked, but there are parts of the application phase space where it is terrible. IoT and TCP do not mix well.
