Is GNU Emacs or Jaeger better?

Neither clearly leads. GNU Emacs starts at Free and Jaeger at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, GNU Emacs or Jaeger?

GNU Emacs starts at Free and Jaeger at Free.

Does GNU Emacs or Jaeger run on more platforms?

GNU Emacs runs on linux, mac, windows. Jaeger runs on Linux, Kubernetes, Docker.

Can I use GNU Emacs for free?

Both have a free tier, so you can try either at no cost before committing.

What is GNU Emacs best used for?

GNU Emacs is most often used for programming with deep lisp-based customization, note-taking and planning with org mode, managing email and file systems from a single environment, long-term, keyboard-driven text editing workflows. Of those, programming with deep lisp-based customization and note-taking and planning with org mode are not what Jaeger is typically brought in for.

What can GNU Emacs do that Jaeger cannot?

GNU Emacs covers Emacs Lisp Extensibility, Package Ecosystem, Org Mode, Built-in Version Control Interfaces. Jaeger covers Distributed trace search, Dependency graph, Adaptive sampling, Pluggable storage.

The short version

Each has a real cost: GNU Emacs steep learning curve for its default keybindings and Lisp-based configuration.; Jaeger tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
They diverge on capability: GNU Emacs covers Emacs Lisp Extensibility, Jaeger covers Distributed trace search.

Where each one falls short

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

GNU Emacs

Steep learning curve for its default keybindings and Lisp-based configuration.
Default UI looks dated compared to modern editors without heavy customization.
Performance can lag on very large files compared to newer editors.
Discoverability of features is poor without prior familiarity or external guides.

Jaeger

Tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
Storage is the real operational cost: high-volume tracing on Elasticsearch or Cassandra is a cluster to run and pay for
Traces alone, without correlated metrics and logs, leave you switching between tools during an incident
