Local is preferred. But.. I'll go Ben and Jerrys cause more variety, and Kapi is my BF.

I've never eaten any Häagen-Dazs ice cream. I've never even heard of it.

Ben & Jerry's is allright, but it's nothing special.

The best ice cream is Cornetto, but I don't know how popular it is world wide.

They are always super expensive, so I usually get other brands. One of my favorites is the Turkey Hill Extreme Cookies and Cream. So chocolatey...

I've tried both the Ben&Jerry's ones but never the corresponding Haagen Dazs ones. I've had caramel Haagen Dazs though and it's pretty great.

Overall I think both are too heavy and sweet though, I love dark chocolate ice cream, that is just ultra choclaty but not too sweet.

How can you not tell how different they are based on the packaging?  They tell you exactly what's in each one.  One is Caramel and Coconut the other is chocolate and vanilla and brownie and the third is chocolate and cheesecake.  If the description is not enough, they have a visual aid to help you.

Unless they add scratch and sniff cartons, I'm not sure how much clearer they could be.

I spend a total of 3 seconds looking at packages and they all look the same. All 3 have white and brown stuff, only difference at quick glance is the difference of light and dark browns.

H-D is great but B&J is perfection

O_o... 

Cocunuts for Caramel.
Brownie Batter Core

If you can not tell what to expect out of each of those ice creams based solely on their names, then the problem lies with you.
