IM+ is a versatile messaging app that supports multiple protocols and offers a customizable interface, while Tencent QQ is a feature-rich platform with a vast user base, particularly in Asia, and strong social networking capabilities. The choice between the two depends on the user's need for protocol support versus social features and user engagement.
