The first thing that comes to your mind is Joop! because all three mostly open with a strong orange blossom note. Shortly thereafter, Original Santal introduces a spicy aromatic mix of spices (cinnamon, coriander, ginger) and wood (sandalwood) with some vanilla. Try wearing Original Santal in hot mediterranean weather to get the full effect - some might even detect a strong "nose-burning" cinnamon note. Theres nothing like this spicy wood effect in Joop or individuel.
I dont think Original Santal is sweet - if you want a sweet Creed, try Royal Delight. Or try the entire SergeLutens line if you have access to it. Serge Lutens Fleurs D'Oranger might initially smell Joop!-ish too.
