I can say that the paid service from ElevenLabs can do long form TTS very well. I used it for a while to convert long articles to voice to listen to later instead of reading. It works very well. I only stopped because it gets a little pricey.

The OpenAI API is ten times cheaper and a fair bit faster.

Also, ElevenLabs keeps diverging for me, and starts mispronouncing words after two or three sentences.
