Butter Pecan vs Mint Chocolate Chip - Cyril, you doubt the divinity of MCC? I... I thought I knew you man... I thought I knew you.
Strawberry vs Pistachio - I admit bias, as my one pistachio experience involved an earthquake. In the middle of the freaking Canadian Shield (aka, as far from any fault lines as you can reasonably get). Understandbly, now that I live on an active fault line, I avoid the nut.
Cookie Dough vs Rocky Road - standard nuts and ice cream votes.
Moose Tracks vs Chocolate Peanut Butter Cup
Rum and Raisin vs Peach
Chocolate vs Vanilla - A good chocolate would probably win this, but most of them are too rich, and I like French Vanilla.
Peppermint vs Coffee
Chocolate Chip Cookie Dough vs Cookies and Cream - My other favourite.
