I don't have them, but thought I'd offer my 2 pennies. I recently changed from Nationwide to State Farm. I have a few properties and 2 cars. Nationwide doesn't cover one of the properties in WV, which is why I had SF on that one, but was reluctant to drop NW cause they've been really good for claims...
Longer story shorter, I bit the bullet and combined everything under SF, and I saved 50% on everything. Literally saved me a couple thousand bucks a year.
Anyway, if you can do a combination policy you could save some money, and the top tier companies may, emphasis on MAY be better to deal with if you have a claim. Side topic about SF, I inherited a house from a family member who had passed away in the house, and had SF for home insurance. It was a situation that required professional hazmat cleanup. SF paid out $30K for clean up, and never blinked an eye. I say this because sometimes having a bigger company might save you in the long run.
