As a tech guy, I suggest you use sails over laravel . This is not because PHP will die (and this will not happen).
As far as I know, everything built on javascript will be faster.
There are many advantages to sails, such as sockets, very easy to implement and so on.
When it comes to a flaw, its only with DOCUMENTATION . It would be difficult for beginners to understand everything.
From PHP (synchronously) to sails (Assynchronous), it takes some time to become familiar with sails.
Make sure you understand the basics of node.js well before starting with sails.
See this , this, and this for more information.
