There're a huge different between a broken feature and the whole server crashing every time that feature is attempted.

Anyway, you prefer critical workflow like payment to show a success but actually be an unhandled error?

For the customer the difference hardly matters, they cannot fulfill what they intended to do, because someone somewhere forgot to catch an exception, going all the way out of the MVC controller, providing a very bad UI/UX, and from security point of view, a possible DOS attack vector.

I prefer an happy customer, and not having to deal with support calls.
