I too went with the 'business class' cable a couple of years ago. In my market, it's dollar-for-dollar slower than the consumer grade (I get 250Mbps where I'd get probably the 500Mbps consumer package for the same price), but in exchange I get an actual SLA that they mostly adhere to. Given my WFH gig, it's worth every penny to have an outage addressed (if not resolved completely) in 4 hours rather than 2-5 business days.
