With the four finalists decided on this season of Dancing With the Stars, who do you think has the best shot of winning?

Bindi Irwin Reveals What She Wants To Do After 'Dancing With the Stars'

At the start of season 21, 13 celebrities took to the ballroom in the hope of winning the approval of the judges and America. But now only four remain to fight for that coveted Mirrorball trophy. Some have been frontrunners since the beginning, while others have steadily improved enough to make them real threats to win.

Let's break down the Final Four and figure out who has the best chance of winning.

'DWTS' Finalist Alek Skarlatos Talks How ISIS Problem Is 'No Easy Call'

Nick Carter and Sharna Burgess

Carter was an early frontrunner this season, tying for the best score of the night in Week 1. While he had a few bumps along the way, he also picked up a few perfect scores from the judges. Some noteworthy personal moments included finding out he was having a baby boy and also recalling his sister's death. He was at the bottom of the leaderboard on Monday, but he could work his way back to the top again.

Bindi Irwin and Derek Hough

Irwin became a co-frontrunner alongside Carter but she has had consistently high scores throughout. This, combined with Irwin's likable personality and Hough's popular as a pro, has made the daughter of the late Steve Irwin hard to beat. But with the pressure mounting, will she excel enough in the final week to win America's votes?

Carlos PenaVega and Witney Carson

PenaVega entered this season with his wife, Alexa PenaVega. They cheered each other on through much of the season but when it came down to a heartbreaking Bottom 2 between the two of them in Week 9, Alexa was sent home. Carlos may not have the most substantial fan base in the competition but he has turned into a solid competitor since the beginning, and could mount an upset.

Alek Skarlatos and Lindsay Arnold

Speaking of someone with a small fan base, Skarlatos began Dancing With the Stars as the least known celeb in the cast. But his workmanlike approach to dancing and his subtle charm caused America to fall in love with him, even when his scores weren't as good as others. His continued popularity has allowed him to advance further than some dancers who received higher scores, so will that continue in the finale?
