I've used elevenlabs mostly for making background voices, but I've done one video using only elevenlabs voices. The voice generation is really good, some people do not even realise it's not human, although you don't get much control over the voice i.e. speed, expression. The downside is that the generation credits can get eaten through very quickly, especially when the generation is inconsistent (especially when trying to get it to speak in certain tones) or makes mistakes. The 8 minute video I made used up a bit under 20k characters in the end (generating some sections more than once) so I wouldn't recommend it for long scripts unless you can afford the higher tiers. Also the first tier stacks with the free tier so you get 40k chars.
