My number one video and image editor is Kapwing. It has a large variety of functions, like creating a gif, putting watermarks on videos and images, creating videos, etc. I recommend it a lot to many. If you have signed up to Kapwing your edited videos or images will not have Kapwing's watermark. If you did not sign up, your edited content will have Kapwing's watermark. That sounds cool. Meaning that there is no need for a premium version.
I consider this one as the best image background remover. Free and provides high-quality images. I've been using Removebg for about six months. But, I am still happy with the experience as I found no issues with the site. I am still looking forward to using it because it is fast and easy to use. Sign up is optional. You can still get your watermark-free content without having to sign up.
