Pros
They keep you moving with good, well-maintained equipment and mostly long runs at a decent, no-nonsense (standard W-2) pay scale. Friendly atmosphere (on the surface).
Cons
They tend to micromanage drivers, which explains why they have inward-facing driver cams. Communication is poor. Important details are routinely omitted, forcing drivers to guess what's going on instead of knowing. Drivers have no steady communications channel, for instead of one fleet manager per driver, a sizable team of nameless fleet managers (well over a dozen) manages the whole fleet. Driver home time is viewed as a necessary evil.
