Best Strains?

I have tried few strains due to lack of a dealer, and I am just starting to grow, and I was wondering, What are your favorite strains? When I say "Favorite" I mean, Funnest, Most Potent, Most PARANOID, Just your favorite strain (preferably a sativa)
and

I love Super lemon Haze by Greenhouse and GrapeGod by next generation but its and indica.

If your looking for a paranoid type, I suggest sour diesel. It is so fucking strong and very long lasting!!

Most functional for me would be Jack herer, and Cinderella 99, (in moderation) since I have attention problems.
Strongest: Purple kush for now.

Depends on what you prefer .. strong strains today, I would get Vortex, C99, Kali mist, Sour diesel ..
