Firebase vs. Meteor for realtime db?

Does anyone have any strong opinions on adding Firebase vs Meteor to an existing project?

I’m just starting to look into the angular-meteor tutorial mentioned in the blog and it looks promising. I am currently using a slightly modified version of this starter project to manage builds: ionic-tabs-starter-sass-jade-coffee and co-exist with ionic CLI. I read here that ngCordova only works with the ionic CLI build process.

Are there any other little details that are not obvious until you dig deeper?

go with the ionic cli process and you will be happy… I am not a big fan of firebase, think it is nice for demos, but starts to get expensive to use in a real app
