Oh, you meant IN orange county.
This really depends on your actual location. OC is a large area, and while one provider may be better than another, not all companies have service in all areas.
Comcast may have underground wiring to your home, verizon may not, for example.
As a general rule, you'll get the best PRICING (not necessarily the best service) by bundling services with one company. Getting tv and internet from the same provider will give you a bit of a discount on both. That pricing ultimately depends on what service you want.
Do you need just the basic channels, or do you want the full spectrum, plus premium services like hbo, showtime, etc?
Do you want basic internet, for a single computer/tablet, or do you have multiple people and devices that are all needing to stream movies at the same time for example?
