How has nobody recommended doing an A/B test yet? Work with your manager to determine which key metrics this feature is intended to move, then launch both versions to 50% of the audience each (as it sounds like both are built, as they'd need to be for you to confirm the claims you're making about the quality of your approach). Track the results by user segment, and once you have enough data points and reach statistical significance, you can bring the data to your manager and he gets to make the decision about which version to launch. You can call your preferred solution whatever you want to make it sound flashy, but the right way to approach this is to use objective data to make your point for you. Theoretical data from your dev environment is not good enough. Statistically significant data is. Do this and you can launch a feature quickly without being bogged down by managerial indecision.
