The one I hate most is PP-Zero Trap. Oh, how I hate it very very very much! It delinks my moves and ruins my strategy eventually.
I love Pitfall traps, since I normally go solo through a dungeon but I hate PP-zero traps like in those 99-floor dungeons!
Out of what I've encountered in dungeons on standard missions, PP-Zero traps are the worst because they practically force you to bring several Max Elixirs and can completely ruin your day if you encounter several in one dungeon. I heard that there is an even worse trap, the Grudge Trap, lurking in Sky's Guildmaster rank dungeons.
For escorting clients, Warp Traps are the worst I ran into because they can (and often do) completely screw the mission up if you lack a Rollcall orb or something to get you to the client or the stairs quickly (and did I mention that you can not tell the client what to do). Though, I can imagine that the Pitfall traps are the very worst for these types of missions because I suspect that they result in an instant failure if the client steps on one.
In quicksave dungeons (Blue/Red Rescue Team), Sticky Traps can really screw you over if they take your last Apple or Escape Orb. I always bring Cleanse Orbs and/or No-Stick Cap into these dungeons to make sure that I can run if I get into trouble. Especially dangerous in Northwind Field because of the Perish Song Politoed that run around there. Sludge traps are not as bad because the resulting Grimy Food can still be eaten, but can be annoying if they take gummies.

Source: BulbapediaWarps all wild Pokémon around the Pokémon that triggered the trap and gives all wild Pokémon on the floor "grudge" status. This usually results in all power points being drained away. This trap is exclusive to certain dungeons in Pokémon Mystery Dungeon: Explorers of Sky, such as Destiny Tower and Inferno Cave.
