This isn't a sign that one architecture is better than the other. It only indicates that the tools are more mature for debugging monoliths than distributed architectures (including event-driven) for tracing causality and data flow through the whole system. The fact that there's great advantages to distributed architectures, yet they're harder to work with, is a signal that there's a market opportunity for better tooling around working with them.
