Well, ************ has superb support I can tell you, they are there for you almost anytime, I've personally dealt with Anthony and Glenn, they are very helpful, didn't deal with Matt much.
However, I must point out that despite their superb support, they need to go through DN, therefore there will be delay in any changes that you needed to be made (anything regarding network) that is unavoidable.
BurstNET in another hand, you are dealing with them directly, which might be better if their support staff don't suck.
But genereally I believe DN has not much problem, you won't have much issue with them them. The final decision is still on you.
I noticed hostingsp was accusing you for spamming, I'd like to know his defination of spamming. Maybe just mentioning someone's name in thread = spamming.
