Google forms do not look great, when someone fills it out you get any email that can go to any folder - social, update, promotions, so it's easy to miss, if you want people to get the link to the slack channel it doesn't always work as expected so it's easy for them to miss, limited functionality, it's not dynamic and has no AI capabilities... That's just off the top of my head. I'm sure I could come up with others.
