How to choose

Choose Kling 3 for longer shots and a square option. Choose Omni for anything that needs references or a clip edit. On price, Omni at 1080p lists at $0.15 per second, which is $0.1875 per second billed, while kling-3 bills $0.14 per second without audio and $0.21 with audio, both at 1080p, so Kling is cheaper per second when you want no audio.

If you cannot decide, send the same prompt to both, keep the duration at 5 seconds, and compare. For a hands-off choice, sume/auto picks Omni by default.
