It depends on what one would define as "better". If you're going for sharpness, sure, Iris and artemis can yield perfectly sharp results but they come at a great cost. Both Artemis and Iris are aggressive skin softeners and denoiser. Whereas Proteus, another popular model for low quality videos, is an aggressive sharpener and dehazer. They all have their own unique qualities, or flaws depending on the person. If it looks good to you go for it. But if the goal is to preserve fine details, such as freckles, and blemishes, then Gaia is the way (1080p and up). Anything lower I don't even bother, waste of time imo.
