Are you trying to just cut out the person with those? Looks like adobe and remove.bg do the best on getting a good selection (edges) but OP's tool does best on selecting just the person.
I am just comparing default output from each tool. OP's tool asks for what object to detect and keep, I had selected human so I guess that's why it only kept the person. But yes, my intention was to keep just the person. For this photo, I would go with Adobe because OP's tool adds a halo like outline all around the person. It would differ from photo to photo I think.
