The business pro support is good, at least for the experience I had in EU. I can call them, tell them my Service TAG and that I need a new SSD, they ship it no questions.
You make a good point but from what I see on YouTube, feel Dell is horrible on the standard consumer end. Look up Linus Tech Tips' Secret Support series or reviews by Gamers Nexus and you'll see that Dell sells terrible products and provides horrible support for them (at least in the consumer market).
