It is also possible that because the entire point of Pearl wanting to fuse with Rose was to one-up Greg, she let that shine through quite obviously while the Rose part of Rainbow completely adopted the Rainbow personality.

I think it is possible for a Gem, with enough willpower put into it, can break out of the fusion personality if they want.
