Our Verdict
For merchants primarily seeking to empower customers to build their own product combinations and offer personalized shopping experiences, BYOB - Build Your Own Bundles is the more suitable choice. Its ease of use and focus on bundle creation make it ideal for stores where product combinations are a natural fit.
Conversely, Opus Cart Upsell Cart Drawer is better suited for merchants seeking a comprehensive cart optimization solution. If you aim to maximize AOV through strategic upsells, cross-sells, and conversion-boosting features like free gifts and reward bars, Opus provides a more robust and versatile toolkit. The higher number of reviews and perfect rating suggest strong user satisfaction and effectiveness of its features. However, strategic planning and testing may be needed for optimal results.
