Ask HN: Best Node.js hosters

For those deploying apps built with Node.js, who - in your experience - provides the "best" hosting service? By "best" I mean reliability most of all, good/fast support, reasonable pricing, and a facility to host non-node apps (such as, say, PhantomJS) alongside the main Node app. We're currently using one provider who'll remain nameless, but whose support is sketchy, provided by someone whose native language isn't English and has difficulty understanding some questions, and whose deploy cycle takes several minutes, and who suffers from periodic outages. Frustrating, and we need someome more reliable. Current candidates include Heroku, Modulus looks promising, but who else would you recommend? Thanks!
