Everything from the 60s to 2018 is probably good AFAIK (which is the only time period anyone credible will talk about if you ask).

Regarding the 2018 incident, I’ve heard 2 conflicting narratives on this subject.

One side, I’ve only seen online, comes across as greyzone/patsoc types who believe anything, or otherwise are just randos repeating whatever 2nd hand rumors they heard uncritically. They say everything is good and that the 2018 incident was a CIA backed coup.

The other side, I know personally via multiple actual Managuan residents, that Ortega raised social security, there were protests, students were gunned down at a university, now the country is under a dictatorship. Things were not necessarily bad before 2018, but maybe the fall of the USSR led to stagnation in actually building socialism (for whatever reason, assume good or bad faith if you want on Ortega). Post 2018, Ortega has made his wife co-president and other weird corruption shaped stuff going on.

My primary sources are not a principled Marxists, but the counter narratives available on the English internet are also not principled Marxists AFAICT.

Nicaragua since 2018 does not appear to be notable in mainstream socialist discourse beyond whatever Anti-Imperialist reasons might apply.

I have been the Pizza Hut in Managua. They have stuffed crust on personal sized pizza, which does not exist in the United States.
