I have used many car services in my years of business and personal travel. I'm not particularly critical to be honest. I just want to get there on time and not have to worry about whether the pickup will be on-time. I used Green Cab in Somerville for many years - they weren't the nicest cars but they were always EARLY and polite.
Pros: Car condition OK. Drivers are friendly.
Cons: Known to be late or no-show. Dispatch doesn't understand customer service.
