What's the best AI video generator?

In the last few days, I have seen many AI tools for creating audio-visual, and even people in my feed shared short movies created by AI (Hollywood will probably cut costs quite a bit in the next few years).

What is your experience with AI video generators, and which ones do you find the best?
(In terms of which AI tools have given you the best video results.)

Here is a pick of tools that you can use for AI video generation:

• DeepAI

• Google Whisk

• Google Veo 2

• Hailuoai Video

• Invideo AI

• Kling AI

• Revid

• Synthesia AI

• Veed

• [some Meta partners can try Movie Gen]
