Managed VPS or managed Cpanel hosting? or Managed VPS with cPanel?
Expecting hand holding where people just do most things for you is overly optimistic. Managed hosting often claims to be such, but if it's not pedestrian stuff that the panel already does, they tend not to go there. [meaning most of what they do if not all is something even a novice can and should get familiar with inside of a few months of being a customer].
Sorry, I disagree on these two companies specifically. Both are fantastic. You can get pretty deep with those guys. I know because I've been a customer of both. They require a panel for support because they deal with a lot of newbs, but they do know the OS, network, webhosting, and the panel very deeply. I agree some companies' idea of "managed" is little more than the cPanel tutorials, but for both WH and KT you do genuinely get the support you expect.
Also, you'll get fast response at 2am - I've been in that situation and they have answered. You don't get that eve with the best non-managed providers.
I give the edge to WT for a few reasons:
(1) WT gives more disk, KH more RAM. I usually find more disk to be useful.
(2) WT as some nice hybrid offerings that KH has discontinued.
(3) WT's base image has more security baked in. Not that KH's is insecure - by no means - but WT goes deeper.
(4) WT's support seems crisper and faster. They also have 24-hour phone.
But really, both are very good. WT is my favorite but KH is good too. I discuss in a little more detail at the site in my sig.
