If you wrangle a lot of in flight changes that are not yet merged into your teams primary git repo, it's very helpful. I have some 10-30 changes in various states at any time. Sometimes they have dependencies on each other sometimes they don't. Placing them all into one branch can work but it's a lot less ergonomic in many ways. jj makes my life simpler because it accommodates my workflow in a way git doesn't.
Honestly, if you don't find it appealing you don't need to use it. I think a lot of folks don't find vim appealing and stick to vscode and that's okay too.
Every time I hear about this megamerge and stacked pr nonsense, it just smells to me. Like, why does your engineering organization have a culture where this sort of nonsense is required in the first place? Anytime I see articles like this gushing about how great tool XYZ is for stack merging and things like that, all I hear is "you don't have a culture where you can get someone looking at and mainlining your PR on the same day"
The jj lovers can go build their massive beautiful branches off in a corner, I'll be over here building an SDLC that doesn't require that.

This is the sort of scenario that leans me towards thinking tools are being praised by how they support major red flags in development flows.
Having dozens of changes in flight in feature branches that may or may not be interdependent is a major red flag. Claiming that a tool simplifies managing this sort of workflow sounds like you are mitigating a problem whose root cause is something else.
To me it reads like praising a tool for how it streamlines deployments to production by skipping all tests and deployment steps. I mean, sure. But doesn't this mask a far bigger problem? Why would anyone feel the need to skip checks and guardrails?
