If it boils down to a matter of personal preference, that's true for almost anything. The author of the actual post that the OP is responding to did not quite get what async behavior meant in node.js - i.e. it's less to do with using process.nextTick() to buy you parallelism, and more to do with async I/O. And, there are other server-side JavaScript engines than just node.js (although it's only node which is getting all the attention), so I wouldn't be making such a generic statement.
