I went full stack since I was waiting for this to show up again. I've been using another similar Appsumo product for the past 5 -6 weeks every day. Right now I'm trying to get a set of slides about 120 seconds each to finish generating audio and have been doing this for the last hour. I hope this is a temporary issue and I'll try again later.

Why this is better than the competition-
1. Cleaner and pleasant-looking avatars with great lighting.
2. Gestures that feel alive most of the time.
3. Great, unique pro voices
4. A clean UI with a good editor.
5. The avatars convey a higher production quality.
6. A custom avatar is included in the top tier. (Not tested but I will)

Why the competition is better:
1. Consistent speed in audio generation.
2. Offer 2 times the character limit.
3. Editor slides are drag and drop.
4. Can duplicate the slides to keep the consistency of the video. (Very Important to me)
5. Faster rendering and the percentage completed are shown so you can generate a longer video and know that it is generating.
6. Unlimited previews with fully rendered video.

I still love this tool but it feels like the UI is playing 'hard to get'. The limit of 1500 characters and not having the ability to duplicate a slide makes this useless for some use cases.
