Eagles vs. Lynyrd Skynyrd - A very tough choice to start off with - Lynyrd Skynyrd but I really like both.
Donna Summer vs Diana Ross - Diana Ross easily
Neil Diamond vs the 70's Elvis in a jumpsuit - Neil Diamond since I hated the 70's Elvis music for the most part,
Grand Funk Railroad vs Jethro Tull - Wow two have my favorite bands. GFR buy the smallest of margins.
Linda Ronstadt vs Carole King - Carole King because she writes songs as well as sings. Ronstadt does have a much better voice though.

Wings vs 70's Rolling Stones (Let's say Sticky Fingers thru Tattoo You) - The Stones - Wings had some great singles but the Stones made some great albums even in their old age. Check out "Bridges of Babylon".
Bad Co. vs Alice Cooper - both are only OK to me but I guess I go with Alice because he wasn't so predictable.

The Carpenters vs Bread - Bread but Karen's voice on "Close to You" still melts my heart
