AWS support is stellar. We have workloads on the three major cloud providers, and AWS support is better by an order of magnitude. If anything, this has spoiled us. When things that take minutes to solve (or figure out) on AWS takes days on another cloud provider, no amount of technical wizardry can make up for it. They won't be dragging your feet just because you have a lower level plan, but if you want to call them to solve stuff right now on the phone or have them showing up at your company with specialists in tow, then you have to fork over the required amount. It's well spent, IMHO.
