Raycast is free (unless you want cloud sync), and I prefer the UI/UX and menu system it uses. I also felt like many Alfred workflows required fiddling and/or were buggy. In general, Raycast's community ecosystem is a much more pleasant experience than Alfred's workflows (in my opinion).

The UX is just nice, and there's lots of little things to like. Result context menus, quick configuration changes, system control, window management, etc. I can type things into Raycast and can reasonably expect something nice to be suggested, e.g. "pi * 6", "1 month", "1 month from now", "sleep displays", "left half", "schedule", the list goes on.

I'd suggest trying it for a day. If you don't like it, switch back.
