Favorite Teams (this list is not completely accurate):
10: Ronald & Christina (Season 12): Leg 2 wasn't very good for them, but I liked watching them succeed later in the Race. They evolved their relationship and improved and that is how the Race should be run (not like TK & Rachel). The team that should have won that season.
9: Lorena & Jason (Season 12): I don't know why, but I liked them. They didn't bicker much and were really strong. I didn't realize how much I liked them until they were eliminated. They were eliminated on the horrible no-bunching leg of their season.
8: Vipul & Arti (Season 10): They got along really well, and never got angry with each other. They were the Kris & Jon of that season, and would have been a fan favorite if they had lasted longer.
7: Oswald & Danny (Season 2/All-Stars): Their accents and the things they said were funny. They were always interesting and should have been in the final 3 in All-Stars (I didn't see Season 2).
6: Brian & Greg (Season 7): They were funny, and almost every leg they would start with something funny to say on the mat. They were also eliminated on the horrible no-bunching leg - ugh!
5: Azaria & Hendekea (Season 12): The strongest team in Season 12. They didn't always get along, but they were good sports and were fun to watch. Their elimination was another bad luck elimination of a team I like.
4: Uchenna & Joyce (Season 7/All-Stars): They learned to work together as a couple in Season 7, and gained popularity with the head shave. And they continued this in All-Stars. I liked this team and they shouldn't have taken that risk on leg 9 of All-Stars.
3: BJ & Tyler (Season 9): I know they hogged the cameras, but they were fun to watch every leg. You never knew what weird things they would do next. They were entertainment that made up for the lack of unpredictability in Season 9.
2: Lena & Kristy (Season 6): They were a tougher team than many may realize - arriving first at multiple locations in their short race. I loved watching the first really strong female team race, and their very early bad luck exit at the hay bales was undeserved. Season 6 would have been better if they had lasted.
1: Dustin & Kandice (Season 10/All-Stars): They were almost unrealistically tough for a female team and they always got along really well. They made themselves likeable every leg, even when they were randomly attacked by Lyn & Karlyn and Charla & Mirna - the two worst teams ever.
Honorable Mentions (in no particular order): John Vito & Jill, Erwin & Godwin, David & Lori, Kynt & Vyxsin, Peter & Sarah, Debbie & Bianca, Hayden & Aaron, Meredith & Gretchen, Kris & Jon, Dennis & Erika, Bob & Joyce, Linda & Karen, Kami & Karli, Steve & Dave, Fran & Barry, Wanda & Desiree, Duke & Lauren
Some of my honorable mentions tied with those in the top 10 - I just couldn't choose between them all.
