If you see one of these symbols at the top of your case, click on it to get the citator report -
If you only have access to one service, you will not likely miss negative treatment (either service will usually identify if your case is no longer good law).
But you might miss other relevant cases that would expand your research and strengthen your argument. So if you can, check both Shepard's and KeyCite. At least one empirical study suggests you will find additional relevant cases by cross-checking.

To use KeyCite or Shepard's to find only the cases that discuss your case for the issue(s) you are researching, look at the headnotes -
You may have come across the B-Cite service in Bloomberg Law, Judicata, or other products that provide citators or citator-like functions for legal materials. The main legal citators, Keycite™ and Shepard's™, are currently the most complete and reliable coverage and for now can be considered "industry standard" in legal practice. When working without Westlaw or Lexis+ access, it may make sense to start exploring other options, particularly the low- or no-cost ones. However, you should be aware that these systems are not generally as robust yet as Shepard's and Keycite.
