Mastodon's federated design and lack of moderation are a huge weakness. I'm white, male, and therefore don't get much abuse.

But Mastodon's idea of how do deal with abuse is literally 'self help', which is not scalable and not viable long term. Some niche communities may successfully migrate, but overall it won't work.

Lot of other architectural problems too.

My recommendation: Keep your Twitter account, when it finally goes chapter 11 and competent management takes over, move back.
