If you're not willing to measure how it helps you, then it's probably not worth it.
I would go even further: if the effort of measuring is not feasible, then it's probably not worth it.
That is more targeted at companies than you specifically, but it also works as an individual reflection.
In the individual reflection, it works like this: you should think "how can I prove to myself that I'm not being bamboozled?". Once you acquire that proof, it should be easy to share it with others. If it's not, it's probably not a good proof (like an anecdote).
I already said this, and I'll say it again: record yourself using LLMs. Then watch the recording. Is it that good? Notice that I am removing myself from the equation here, I will not judge how good is it, you're going to do it yourself.
