Feature set. The SDK needs to perform the functions that you need (background replacement, virtual try-on, etc.)
Platform support. Some SDKs like Banuba Face AR SDK support native Android and iOS, as well as Flutter, React Native, Web, and Desktop. Others are limited to one or two platforms.
Documentation. If there isn't enough documentation, you might spend an unreasonable amount of time integrating the SDK which defeats its main purpose.
Price. Depending on whether the product fits your vision and helps achieve your business objectives, the same price could be too much or too little.
