However, merchants with simpler checkout customization needs and potentially lower traffic (given the limited reviews on App 1) might find 'Checkout Blocks & Customizer' sufficient, especially if they prioritize ease of use or have a smaller budget. The limited data on App 1 makes a definitive recommendation difficult without further information.
