I've read both sides of these arguments everywhere, leading me to believe both sides must hold some degree of truth. The problem with these "arguments" is they are mostly from experience. It's difficult to argue with experiences which are true if they happened. The bottom-line is node has the capacity to be awesome and to suck. The only option is to find out where you and your project fall after trying node for yourself, but if one thing is for certain, node will do better focusing on minimizing bad experiences no matter how they happen. Now most new frameworks recruiting users begin their pitch with promising a better experience (than node).
