From what you have said, it sounds like the only constant in your comparison
was the bridge. That's kind of like asking why one coil using a particular
spark gap produces weak sparks , when a different coil can produce strong
sparks using the same spark gap.
We would need more details of the other components as well as an explanation
of how you determined "for sure" that both setups were ideally tuned before
guesses could start to become useful analysis or diagnostic test
suggestions.
There is a thread on 4hv dealing with low impedance vs high impedance DRs.
A low impedance setup will typically have a much larger primary cap than a
similarly sized high impedance primary - and then the secondary can also be
high/low impedance. Multiple coilers have successfully demonstrated either
approach - spark length is still primarily determined by input power for a
well designed and built coil.

Subject: [TCML] solid state tesla coil question
I recently finished the minibrute tesla coil and have it running well. The
question is why does this coil operate better with a large primary capacitor
size of .21uf vs. a smaller cap size of say .005uf. I have tried this setup
two different ways by using two different secondaries and at .005uf the arcs
are very weak and small. At .21uf the arcs are bold and long. I know for
sure that the primary and secondary were in tune on both setups.
