TDMS are good if done right. Class TDMs give a variety to the player knowing that each class has its one strength and weakness. The "pick you weapons" types are only good if you know what you are doing, for example you select your main weapon, warp to another room and so on. The "You're stuck with what ever you get" ones are bad they have no variety and have the time there will be a powerfull weapon included. If you don't know what I mean by "you're stuck with what you got" it means the weapons there are no weapons around and you get what weapons you spawn with. Have I made myself clear?
