Fully-managed VDS: LiquidWeb Or MyriadNetwork

Our company may be going the Linux route, so I'm in the market for a Linux VDS that's fully managed. I've never utilized a fully-managed service, so maybe you guys can help me out here.

I used to have a shared account with LiquidWeb (up until a week or two ago actually), and I didn't have any complaints there. However, I've never used their VDS service.

I've had a VDS at MyriadNetwork for almost a year now, and they're one of the best--if not best--providers I've ever done business with; very prompt ticket responses (less than 10 minutes on normal-priority tickets), very friendly and helpful even if it's your responsibility.

I'm aware that LiquidWeb includes full management in their price, whereas MyriadNetwork offers it for an additional $75/mo. A fully-managed comparable plan at LiquidWeb is about 50% cheaper than Myriad's. I know from experience that Myriad's higher prices are justified with the service they provide, but I'd like to know what everyone here thinks.

Should I choose Myriad and hope their full management service is as good as their VDS service, or should I try LiquidWeb out and hope they deliver? Has anyone used either provider's fully-managed services?

Please move this to the Managed forum if it's more appropriate; I picked this one because my situation deals with two very specific VDS providers.
