Kanto's Safari Zone is the best because it has the least fluff.
Hoenn Safari Zone added an area that is only accessible by acro bike forcing you to backtrack to Rydel in Mauville and change bikes. It aLao added Pokeblocks to attract Pokemon of certain nature yet the games provide almost no info on how to manipulate the nature.
Sinnoh Safari Zone added marsh tiles and rotational Pokemon to umm... waste players' time?
HGSS Safari Zone added customizable maps to increase frequency of certain Pokemon but locked items and Pokemon behind time gates. You also have to wait until Boaba calls you a certain number of times.
