Streamer propagation and corona are certainly very different, and
certainly positive streamers develop better. But
initial breakdown voltages are not significantly different.

Makes sense. The smaller ball in the positive terminal forces
a positive streamer, that propagates better than a negative streamer.

I only see differences in streamer propagation, and in the electric
field required to keep a streamer propagating. Nothing about initial
breakdown electric field, that doesn't have reasons to be different
at positively or negatively charged surfaces.
