As someone who is actively working on using SAM, I would say that it leaves a weird border (2-5 pixels wide) of the cut out object so depending on the tasks, it may or may not be suitable. And in the demo, the server returned a way better image embedding than the open source one from Vit_h. There are a lot of issues on github talking about this. So take what you see on the demo page with a grain of salt.
