I think (would) is more formal than should.
We usually use (should) to obligate a person to do something.
this my opinion :)

In modern english, we won't use "shall" and "should"
to instead of "will" and "would"...but in old style english, especially in British English, I, we, they were followed by should, others were followed by would, this is what I learnt from the Educational TV programme.

I voted for i should be very grateful....
I would be very grateful
I might have misread the whole thing. I'm definitely aware of the older/formal usage of should.
But in a current context I might say "I should be grateful for it, but I can't." It refers to something that's supposed to be the case but isn't.
Or "I would be grateful if ..."; there's a condition to it, but it might happen.
Not too different I suppose ...![]()
I do still use it sometimes in writing.
"Should" sounds more formal to me.
