Powerless Panther w/o his fancy tech did this:
Not an actual fight, but it still took only 2 strikes to stun Luke and knock him down on his ass.
And Luke noticed earlier how [powerless] Panther seemed faster than Daredevil to him.
In a forum fight, T'Challa has his superhuman physicals, ranged weapons and the suit which will protect him from Luke's blows (assuming he would close the distance between them and connect with his punches).
