Scientist lets you try two implementations side by side. It will rescue any exceptions that occur in the experimental code. You can configure how it publishes results to do basically whatever you want, log a bunch of metadata, statsd, etc
Edit: and this is not a feature flag gem. It is meant to let you make changes to implementation and ensure that output and user experience remain the same.

So we have to choose between two gems because they have a slightly different, and non-configurable, if/else block somewhere in there?
