Just to add to this... the real diff is that trips are more vulnerable than a set and less disguised. They're vulnerable 'cause you've got a paired board giving you real exposure to a full house. It's usually been suggested to me that trips need to be played hard and fast -- not a good candidate for slowplaying. Other issue is that you might want to stay aware of your kicker... 93 on a 996KT board has exposure to not only KK and TT, but also villain holding 98 or A9. This isn't an issue with a set...

A set is more hidden and can even make sense to play against a strong flopped draw (i.e. 3 to a suit) because you have the outs to a full house. Still have to be careful about slow-playing them but you have the option depending on board texture.
