Destiny's stargate can dial the nine chevron address to Earth if it has enough power. We know this isn't a power issue - the ship can fly through a star after all, pretty sure it can compete with a Naquadah generator to power a gate. What makes the Destiny gates 'less advanced' is the fact that they can't dial beyond a certain range they can only dial 'planets in range' which usually only number in the 1-4. Just rewatched Stargate Universe and something they said at the beginning of S1 confused me: They stated that the stargates seeded by the seed ships and the one on board Destiny were 'less advanced' than the Milky way or Pegasus models.
