Delta wing and Canard vs 'Conventional'

[msbbarratt]

The canards are useful for improved manoeuvrability at high angles of attacks as they're not masked from clean airflow by the wing itself at such attitudes.

I don't see that a canard is necessarily unstealthy, it depends what you make it out of.

Delta wings were considered by some designers in the old days to be a bad idea. Maybe that opinion stuck amongst the American design community. There's pros and cons to any wing design, and there's no real killer reason to choose a delta or something else. But I guess if one chooses a delta wing, canards make a lot of sense too.
