First of all "Man I Feel Like A Woman" is one of the worst country songs ever written. I don't care how many albums it sold.
Second, in Carrie's defense, she is a college student with very little experience performing on stage. While, Bo has been performing with his band for years.
Bo has a great voice. I never implied that he doesn't, but for me, he always sounds the same. I think Carrie has more range, and I think she'll get better on stage as she gets more experience, and there's not so much pressure, and she can loosen up.
Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be enbered with your old nonsense. ~ Emerson
