Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Notepad++

Windows-only, with no official native macOS or Linux build.
Lacks built-in debugging or project/build management found in full IDEs.
Plugin quality and maintenance varies since they are community-contributed.
No built-in version control integration beyond what plugins provide.

OpenSearch

Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
Overkill for plain application search, where a dedicated search engine is far simpler
