Metahuman Face_AnimBP

Hello, dear!
I have a question related to organizing face animations in Metahuman using the Face Anim Blueprint.
I see two options: using a state machine with additive animation and using montages called from the character.
The state machine generates a lot of connections and repetitive rules, while montages do not overlap with each other (I have a base emotion, a short additive animation, and lip-sync).
