Fire dungeons always have lava, obviously. They rely more on difficult enemies than puzzles. Examples: Fire Temple(OoT), Goron Mines(TP), Earth Temple(SS)
Forest dungeons usually have simple puzzles, and are usually early in the game. Examples: Deku Tree(OoT), Forest Temple(TP), Skyview Temple(SS)
Water dungeons usually have the hardest puzzles, and obviously a lot of water. Examples: Water Temple(OoT), Lakebed Temple(TP), Ancient Cistern(SS)
Sand dungeons usually come later in the game, and have quicksand. Examples: Arbiter's Grounds(TP), Sandship(SS), Lanayru Mining Facility(SS)
Mechanical dungeons have a lot of technology in them. Examples: Sky City(TP), Lanayru Mining Facility(SS)
Ice dungeons have slippery ice floors. Examples: Snowpeak Ruins(TP), Ice Cavern(OoT)
Dark dungeons usually have lots of traps, and a creepy atmosphere. Examples: Shadow Temple(OoT), Twilight Palace(TP), Ancient Cistern(SS)
My vote goes to fire, ice, and mechanical.
