So, one of the differences between Rahu/Ketu and other planets is that Rahu/Ketu are not lord of any sign, though they continue to be the co-lord of 2 signs. Rahu is co-lord of Aquarius along with Saturn and Ketu is co-lord of Scorpio along with Mars. That's why, Rahu is known as shadow of Saturn and Ketu is known as shadow of Mars. Another thing is that Rahu/Ketu takes up the character of the planet which is sitting with them.
Now, Rahu gives results during its Mahadasha more on the basis of house it is sitting in rather than the sign it is sitting in. For example : Rahu is in 10th house in the sign of Leo. So, this person will get more results related with Work Environment, Fame and Social Status (10th house related things) than results related with Leo related things.
Rahu represents illusion, obsession, medicine, drugs, foreign things, fame, movies, TV, Online world, Cheating, Alcohol etc.
So, now it depends on which house Rahu is placed and what time Rahu Mahadasha is going on. Like, if Rahu is in Upachaya Houses (Houses # 3, 6, 10 and 11) and person is going through Rahu's Mahadasha during his teenage then its effects may not be too good unless there is some other benefic aspects, because Upachaya Houses improve with time and start giving good results in 30s. But if he goes through same Rahu's Mahadasha in 30s then person will get better results. But in both cases, person will be obsessed about the things related with the house where it is placed.
So, Rahu will basically make a person obsessive about the things related with the house in which it is placed. Like in 5th house, the person may be obsessed about Sports and Creativity, in 3rd house it makes a person very action oriented, this person cant sit quietly, in 10th house person wants to achieve fame and social status.
Rahu also represents cheating, so under Rahu Mahadasha there is a great possibility that people related with the house where Rahu is sitting may cheat you. Like in 10th house, people of your work environment may cheat you, in 9th house, your spiritual gurus may turn out to be a thug and in 3rd house your close neighbours may cheat you. There is a strong possibility that someone may be under illusion about his life during best part of Rahu Mahadasha as it is an illusionary planet.
Sign wise - Rahu gives best results in earth signs, i.e. Taurus, Virgo and Capricorn. Because here, the obsession of Rahu finds stability of earth and doesn't take wrong path to fulfil obsession.
Rahu gives good results in Air signs, i.e. Gemini, Libra and Aquarius. Here they become good communicator and famous in Movies/Media world.
Rahu doesn't do too good in Fire signs, i.e. Aries, Leo and Sagittarius, as the obsession is now meeting fire and making it double dangerous.
Rahu is not so good in Water Signs too, i.e, Cancer, Scorpio and Pisces. As obsession is not finding its stability in water, these people flow with their obsessive ideas.
