What out of state moving companies can I trust?

I’m moving 770 miles and I’m trying to find a good reliable company. I’ve talked to two people from two different companies (united states van lines and world moving). Both seemed very nice and informative, but I just went online to look at reviews for the companies and they both had HORRIBLE reviews!
So has anyone recently moved and had a good experience with a moving company?
And what are the most important questions to ask a company before I sign anything?
