Tents. Caravans take the fun out of it.
Dogs or cats?
Dogs or cats?
White tea. Green tea tastes like grass.
M&Ms or Reese's Pieces?
Depends on the movie, but I'll go with ghost because of my love for the original version of The Eye (scariest movie I have ever seen, hands down).
Iron Maiden or Judas Priest?
Megadeth, obviously!
Manual or Automatic?
Maiden. The only Priest album I really like A LOT is Sad Wings of Destiny, and that's not enough to turn the tide.
Metallica or Megadeth?
No love for Painkiller? That's one of my favorite albums of any band. I also have much love for Screaming For Vengeance. However, I'd still go with Maiden. Their first 7 albums are unstoppable.
For the other question, I'd go with Megadeth overall, but Metallica if they all committed ritualistic suicide after And Justice For All, never to record anything after 1988.
Carry on.
