What is better? VsCode VsCommunity or QtCreator

I ended up using VSCommunity and the autocomplete/intellisense takes about 10 seconds to suggest anything, it also takes a long time to remove the red underlines from perfectly good code.

I searched the forum here and found instructions that might fix it, I have not tried this yet:

Another problem I am having is that it doesn’t seem to recognize everything for unreal, things like “UCLASS” are not suggested at all. Is there a way to fix that problem too?
