As someone who used to use Meteor, I'd recommend not using it at all.
Meteor is amazing and great... until it isn't. The power of Meteor is the amount of bare metal things already implemented for you (DB management, for instance)
But the moment you need to do something a little weird or want to do things different, it becomes almost impossible.
Use something, anything (besides I guess RoR) besides Meteor in my opinion. It locks your code in and becomes impossible to leave without re-writing everything.
We use Meteor for our production products. I've personally been using it for 3 years and love how easy it is to get up and going. With all the changes made in 1.7 and 1.8 its been really great to use. Scaling is a bit of a pain in the ass but with Heroku and Mongo Atlas its eased that burden. Meteor just simply provides so much out of the box and has great community support. You can extend Meteor pretty far.
As for 2019 and onwards, I would recommend it personally, very quick to get it up and running and putting things into production. Its the community that keeps Meteor alive so I wouldn't depend on MDG for your opinion cause they more or less already shifted their focus on Apollo.
I use it for a client's project, although it's managed by another dev, who introduced it to me.
I haven't dug deep into it, but I like the opinionated choices and the "batteries included" approach. It allowed us to move very fast in the early design steps. But it will probably require a rewrite for scale, time will tell..
In that rapid prototyping / MVP approach, I haven't yet reached the point where it's more in my way than helping out as @madamelic mentioned.
