The best tree checker tool: your own common sense.
Other things that significantly cut down on errors:
- Not relying on transcriptions of others.
- Reading the actual record.
- Using automatic import features.
- Remembering that before 1880, relationships are not given in census records.
- Remembering that census relationships are given in regard to head of household.
- Not indicating a record gives details that it does not.
- Assuming the compilations of others are correct.
- Periodically manually reviewing your data.
Tree checkers can get the obvious errors, but they rarely catch it if you merged two first cousins of the same name into one person. Don’t expect the computer to do all the thinking for you.
