Honestly, they aren't very helpful, unless you have coverage from multiple sources/companies.
And you don't need official coverage to get something similar, especially if you live in LA. Most of the people who do coverage are 18-25 year olds just out of high school or college. Assistants working full time jobs, that likely would rather be doing anything other than coverage.
For many screenwriters, that is your peer group that you hang out with in your spare time. If you really want "coverage" from multiple sources, give your screenplay to half a dozen of them.
As for wanting multiple coverage on other people's work -- that just seems like it would be one more distraction, one more reason not to write, one more thing that seems like it may hold a key, but it really is only one more thing to obscure your vision on your real goal: writing a screenplay.
Just know that different people have different opinions. That one person can dislike a script that the next loves. That's really all to get out of seeing multiple coverage samples.
CAVEAT: If you do end up looking at multiple coverage(s), you'll notice some people are much better at crafting a logline than others. Remember, loglines in coverage are generated from a reader that has simply read the script. Some people can write a summary that feels like a movie, where other can take the same material and make it feel like a blueprint.
The sad truth of the matter is that the writing skill of the person doing the coverage often has a bigger impact on your career than your own writing.
Coverage is not a writer's tool. It is a producer's tool to pretend that they have actually looked and the material and feel comfortable saying, "No," to more work than they could possibly read in a lifetime.
