My Two Favorite Records of All Time, a Tie!

Black Sabbath's "Black Sabbath", and Metallica's "Ride the Lightning"; no 1a and 1b here, i just can't ever decide, so they both are---Now here's the thing, my #3 and #4 certainly are Heaven and Hell's "Heaven and Hell"[for purpose at hand, we'll refer to Dio era Black Sabbath as Heaven and Hell, though there's many ins and outs there] and Megadeth's "Peace Sells, But Who's Buying"; "Black Sabbath" beats "Heaven and Hell", and likewise with Metallica versus Megadeth because, without Sabbath there'd be no Heaven and Hell, and without Metallica there's a good chance there's no Megadeth. Please cast a vote, and any thoughts, ideas or just opinion WELCOME!! \m/
