Allstate here, mostly for the convenience of having the agent in my Manhattan neighborhood. I don't carry car insurance, so I've no idea if it's a good deal as a package.
Never had to use the condo insurance though. We did have an incident in which one of our hired hands fell off of a penthouse roof doing something he was expressly told not to do. He broke many important bones and sued 9 of us for a total of $50,000,000. Ultimately he lost the case, but when the suit was filed our lawyer asked us to send proactive letters to our insurance agents. My agent let me know I was covered, whatever the outcome of the lawsuit.
