Saying they are all the same when no fidelity is lost is missing the point. The only distinction between logs, traces, and metrics is literally what to do when fidelity is lost.

If you have insufficient ingestion rate:

Logs are for events that can be independently sampled and be coherent. You can drop arbitrary logs to stay within ingestion rate.

Traces are for correlated sequences of events where the entire sequence needs to be retained to be useful/coherent. You can drop arbitrary whole sequences to stay within ingestion rate.

Metrics are pre-aggregated collections of events. You pre-limited your emission rate to fit your ingestion rate at the cost of upfront loss of fidelity.

If you have adequate ingestion rate, then you just emit your events bare and post-process/visualize your events however you want.
