The short version

Each has a real cost: Dask each Dask task carries between 200 microseconds and 1 millisecond of scheduler overhead, so graphs of millions of tasks add 10 minutes to hours of pure overhead; Fathom team plan requires minimum 2 users; cannot purchase single seat at team pricing
They diverge on capability: Dask covers Parallel computing, Fathom covers Auto-recording.

Where each one falls short

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

Dask

Each Dask task carries between 200 microseconds and 1 millisecond of scheduler overhead, so graphs of millions of tasks add 10 minutes to hours of pure overhead
Partition sizing is left to the user: chunks must fit several times over in worker memory, and both oversized and undersized chunks are documented failure modes
Embedding large locally created DataFrames or Arrays into a Dask computation is documented as a practice to avoid because of network overhead
Calling compute repeatedly in a loop rather than batching prevents parallelisation of queries
The documentation itself advises trying better algorithms, file formats or sampling before adopting Dask

Fathom

Team plan requires minimum 2 users; cannot purchase single seat at team pricing
CRM field sync and deal view summaries available only on Business plan ($34/user/month) and above
