My (also anecdotal) experience has been the complete opposite. Any time I've rented from a large company (or have spoken about this to people who do) I have dealt with frequent rent increases, lack of responsiveness to issues, and many other problems.

In 3 weeks. At 11:15 AM. On a workday that you have an important meeting at 11:30 AM and cannot miss. Oh, you need a different date? Well, how about in 2 months at 11pm on a Sunday? Of course, we won't be able to actually do any of the work that late because of noise issues, so you'll need to schedule a follow-up maintenance appointment. (I'm only roughly paraphrasing what happened to a friend when their dishwasher broke.)
On the other hand, renting from a private landlord who's renting out their old home or similar has been much more fruitful for me. Perhaps it's because I spent the time to vet the landlord a little bit as well.
There are good management companies, and there are bad ones. There are good private landlords, and there are bad ones. Companies, and more specifically the people at those companies, also take things personally.
