The Classic:
"Crimson and Clover" by Tommy James & The Shondells (1968).
I've always liked this song. I was in a mood to listen to it tonight, which caused me to discover that there are two covers. Since there are only two, ranking them will be easy!
I like the original because of the phaser effect (such as at 2:25) that gives a dreamy feeling to the song. I like the way the song alternates between longing and confidence, sounding first wistful and yearning before becoming more energetic and excited then reverting to yearning again. A sweet, intriguing song:

FIRST PLACE: Joan Jett and The Blackhearts - "Crimson and Clover" (cover)
She's hot, what can I say. I mostly just spent the video watching her and forgetting about the music. But when I paid more attention to the song, I thought that it's interesting to hear a woman singing it, since the song is about being in love with a woman. I'm glad they didn't change the lyrics to try to make the song hetero.
I feel this cover sounds stronger and more seductive than the original...less wistful, more confident and raunchy. It's a very good cover, although I prefer the classic's subtlety and variety of sounds.
DEAD LAST PLACE: Prince - "Crimson and Clover" 
I don't like this cover at all! I don't like the placid drum beat, I don't like the electric guitar warble that makes it sound Country to me, I don't like the boring electric guitar solos that sound like a zillion other electric guitar solos I've heard.
And YIKES! I
really don't like Prince's voice in this song! His voice sounds too warbly, whispery, and whiny for my tastes. I view the song as being just a step above elevator music. That's not good, because I really don't like elevator music.
Ah well, here is the video below. If you're a knitter, keep the needles farrrrr away from you so that you aren't ovecome by the sudden, desperate urge to jab them into your ears and end your awareness of this song:
