The Meteor marketing team seems to want to entrench themselves in every naive tech company they can and I can't believe that there could be so many Meteor users here with enough experience to comment so stridently on it.
My experience with Meteor was that my current company hired someone (who is/was literally writing a book on Meteor) to be the lead dev and they built a whole dashboard application in Meteor.
I arrived 6 months later and began working with them on that application and another Express app that they flat-out refused to touch.
I found that though Meteor was easy to pickup and figure out at a surface level, that it got very complex very fast when you started down the path of making a large application with lots of moving parts. Performance was terrible and there were always strange quirks and assumptions that Meteor would make that needed to be worked around later (one instance was their use of random string _ids in mongo which weren't valid ObjectIds).
Meteor tries to do everything for you and when you want to do something different, you have to go find some esoteric knowledge to hack around some core architecture or pattern. They don't play well with others and any questions or criticisms I had for this Meteor evangelist usually resulted in abstract arguments that boiled down to me needing to change my entire way of thinking about web apps to work with it effectively.
One of my arguments was "hey, where are all the other meteor devs? what happens if you leave or get hit by a bus?" which was also deflected somehow or made to sound ridiculous...
4 months later they leave to start their own consulting company and try to get themselves hired as an outside consultant for whatever rate.
I rewrote the entire application with a MEAN stack in 6 weeks with more features, better performance and a decoupled architecture and we've never looked back.
Admiral Ackbar would recognize Meteor for what it truly is... but unless you've got a Jedi or 2 on your team you'll want to be double and triple checking your needs before moving forward with Meteor.
