Why was this first compromise actually favoring the Republicans?

Either the 3/5ths compromise or the Bill of Rights

Explanation:

The Federalists wanted slaves to not count as citizens so they could have more congressional support. The Democratic-Republicans wanted them to count as a full person to gain more congressional support. They came to agree on them being slightly over half.

The Bill of Rights was a compromise because the Democratic-Republicans did not believe that the Constitution did a good job stating the rights of the people as they had a much stricter interpretation of it.
