Dissapointed that Canvas Background tool works better than PS's

I'm a 15year + photoshop user. HOW is Canvas Background remover better than PS's own select subject to remove background. I'm working with some intricate clipart to remove full background - I  use select subject/ remove background, but still need to refine all the little nooks and crannies, which grated doesnt take long in PS, but I pulled the same image into Canva - hit the remove background tool - and the background was fully removed - clean as a whistle in one second. I feel Adobe is dropping the ball here 😞

Products from other suppliers are sometimes working better on specific problems. It's the overall experience that is important.
