Basically you can go quickly from the log to viewing diffs or any other action on commits or groups of commits and more.
I used to only use git from CLI for 10+ years but mostly only use magit now.
I care because I know the values of those programmers in a narrow scope and won't be as annoyed when I inevitably have to go debug the rust code instead of C.
However, that values statement was challenged by automatic binary downloads without user confirmation.
Luckily the fix is already in progress, but its concerning it was ever implemented.
