I'll bite: me. They take great care of me. I've got a gigabit ethernet circuit running a thousand miles or so (Knoxville to Houston) that never even hiccups. My 150/20 HFC circuit has seen maybe 30 hours of downtime over the last five years. Pricing on both is quite good (I actually couldn't believe the price on the gigabit circuit).
Their project management does leave a little to be desired (I was VERY frustrated with the PM on the gigabit circuit install---her communication skills were lacking, and she seemed to have no concept of deadlines) but the pre-sales guys (both sales and engineering) do a hell of a job, as do the field guys, and the back end guys I talk to.
