After many problem with GoDaddy Manage VPS hosting account.
I Have now been with A2 (Manage VPS hosting) for more then 2 years now.
The few time I have had any problem, it has been resolved with very short respond-time, and always in a very professional way.
Been with WPMUDEV for many years now, and every-time I use their support im impressed. It does not matter if its a technical or a administrative question, the respond-time is ALWAYS very good.
If you working with Wordpress, then this is a membership that always should have.
