Delta wing and Canard vs 'Conventional'
In the literature the terms canard and fore plane are used interchangeably.
Whether a canard offers advantages comes down to the usual engineering and aerodynamic trade offs. With a canard the wing can not reach its max CL and be allowed to stall before canard stall, though I guess that may be obviated with an all moving canard as on the Eurofighter.

One interesting development in foreplane technology was experiments with longitudinal positioning, i.e. varying the fuselage station and centre of gravity to get the best compromise of strength vs. manoeuvrability.
Starting from a significantly rearward position, aerodynamicists tried incrementally moving the foreplane forward on a specially built test vehicle, which initially gave improvements which peaked, then started to decline.
At this point, the testing scientists declared "This is too far canard."

Don't any of you recall the mach 3+ XB-70? It had delta wings with outer sections that could be rotated down in flight. And it had huge canards with trailing edge flaps. All way back in the early 60's.
