I have specifically qualified my statement to cross-posts that include the "RT" text and all sorts of broken references to avoid "not all cross-posts" responses, but I still got them. Okay then.
Unsurprisingly, I indeed believe that Mastodon is better than Twitter, and prefer seeing posts created here over posts created somewhere else.
I also think that the ability to cross-post from Twitter works against Mastodon adoption.
