After having auto insurance with Progressive for the past few years, I thought I'd give the others a try, or at least revist a few quotes.
Seeing dozens of ads on Internet sidebars promoting Allstate insurance, I figured, what the heck; maybe they've got a deal for me, assuming they're trying to get new customers, hence the numerous Allstate ads.
Allstate Auto Insurance: I visit allstates web site and get an online insurance quote. Though the quote was a $100 more than Progressive, the user interface was very intuitive and easy to use; it was a breeze getting a quote, ... but... the price a bit steep. I closed out Allstates' site and went back with Progressive (mind you, I didn't have much time to search).
