I only know this
https://www.sofascore.com/ and
https://www.flashscore.com/ looks different from the first flashscore but haven't explored the features they ,just see and closed ! because if I only want one match ,then I'll write on google for example "xxxx vs yyy" will open their live match and get a notification if there any goal ,simpler for me personally and the feature is already on my mobile ! reading the details from you it seems Aiscore and goaloo is worth it I'll try ,thanks
