In the era of technological dependence and globalization, online banking plays a pivotal role in everyday financial transactions. This research offers a comprehensive comparative analysis of online banking services provided by five prominent Philippine banks, namely Bank A, Bank B, Bank C, Bank W, and Bank X, and two widely used mobile wallets, Bank Y and Bank Z. Focused on customers' preferences in the National Capital Region (NCR), the study employs a mixed-methods approach, combining quantitative data collected through an online questionnaire with qualitative insights. Statistical analysis, specifically the Kruskal-Wallis Test using SPSS, is applied to identify significant differences among banks and mobile wallets. The research findings reveal that Bank B is the preferred online banking service, closely followed by Bank Z among mobile wallets. The study identifies five critical factors shaping user satisfaction: Convenience, Safety & Security, Ease of Use, Trust, and Usefulness. These factors significantly influence the overall user experience in online banking. The study emphasizes the urgent need for NCR banks to enhance their online services to meet customers continually. The study highlights variations in the performance of different banks, identifying Bank B and Bank Z as standout choices for users to use. The study recommends continuous improvement in online banking services, emphasizing technology investment, user-friendly interfaces, time-saving features and prioritizing convenience, safety, and ease of use. The study suggests broader research areas, including expanding the banks, demographics, and analytical tools, to inform financial technology decisions and establish leadership in NCR's digital financial landscape.
