Lost in the Supermarket

How does one select his toothpaste? Really, I had to replace a tube of whatever (Aquafresh) last night, and I spent five minutes staring at all of the selections. Do most people have a go-to brand? Say the one that their parents always used? Am I missing out, does one minty paste taste better than another? Sometimes these questions plague me, although I feel bad for the woman who was having trouble deciding which type of adult diaper to buy.

And for the record, I bought the major brand that was on sale. Paste, not gel.
