I have also done extensive work on both (I'm much older than the word microservices) and have found advantages to both approaches depending on requirements.

I've also found that most so-called monoliths still often end up breaking apart components anyway. I've only seen true monoliths as described above in the mom and pop type IT shops where there's only a couple support staff and they don't have the resources or experience to properly break things out into separate resilient components. And yes supportability is definitely a valid part of that design call.

Again that was just one example of a potential advantage to it while admitting there are trade offs. Others here have given better examples such as at larger orgs where multiple independent teams get involved with a single app.
