'Dancing with the Stars: All-Stars' Finale: Who Should Win?

Kelly Monaco, Shawn Johnson, and Melissa Rycroft (ABC)

After weeks of shimmying, shaking, and samba-ing, it's all come down to this: Kelly Monaco, Shawn Johnson, and Melissa Rycroft will compete in tonight's first-ever Dancing With the Stars All-Stars finale.

Monday's performance finale will feature two performances from each finalist. All three couples will perform their favorite routine from the season, as well as a super-sized freestyle that can feature extra performers, and no holds barred lifts and tricks. So which lucky lady looks poised to walk away with the mirror ball trophy? Let's break it down.

Shawn Johnson
Why She'll Win: The most technically skilled performer in the competition already has one DWTS trophy and she's been a fan favorite all season long. The addition of fellow Olympians the Fierce Five to her freestyle routine with Derek Hough should go a long way in securing her a second title.
Why She Won't Win: If Johnson's fan base doesn't turn out in full force, she could easily be brought down by one of the other two talented ladies.

Kelly Monaco
Why She'll Win: The General Hospital star has dynamite chemistry with partner Val Chmerkovskiy and she's been steadily stepping it up all season long. And you should never underestimate soap opera fans — they are a seriously devoted bunch.
Why She Won't Win: Monaco is the only finalist to have not yet scored a perfect 10. Her movement style is also distinctly less elegant than her competitors.

Melissa Rycroft
Why She'll Win: This former Bachelor cast-off has a sparkling personality to go with her seriously impressive dancing skills. Her partnership with Tony Dovolani has been a joy to watch all season long and this pair certainly has enough enthusiasm to take them all the way to the top.
Why She Won't Win: Most experts thought she wouldn't make it this far, so the former third place finisher is definitely this finale's underdog.
