Would be interesting to see Meteor stats there too

Heavy base library, so custom build only saved about 5% for us.
Good response rate to support issues, although sometimes valid issues are not fixed so we require custom workarounds to basic problems.
Great for POC, or pilot. Not so great for consumer apps using WebView IMHO.
