None of the mainstream providers are going to be very much different.
Comcast was my ISP and I had outages that lasted for days over the span of 6 months because they didn’t want to send anyone out to do the wiring work that needed to be done on my building.
These are all really large companies and are going to display profound levels of dysfunction which will affect the customer negatively, repeatedly.
Go into the situation understand that any big ISP is going to give you some headaches and try to be patient.
