Two different types of banking systems, Islamic and conventional, dominate the banking structure in Saudi Arabia. The purpose of this paper is to contribute to the ongoing debate as to which of the two is better. Using data for the period 2014–2018, the study compares Islamic and conventional banks. It combines traditional financial ratios, Return on Assets (ROA) and Return on Equity (ROE), with Data Envelopment Analysis (DEA) to perform a comprehensive analysis. In terms of ROA, the performance of conventional banks is better than that of Islamic banks, but in terms of ROE, vice versa. DEA results show that conventional banks are more efficient than Islamic banks. In fact, in terms of ROA and ROE, Al Rajhi Bank, an Islamic bank, is the best performer. But in terms of efficiency scores from DEA, Al Rajhi ranks seventh among all banks, while NCB, a conventional bank, ranks first. Issuing shares and utilizing funds in profitable options, such as loans and advances to increase net income, are the policy recommendations for Islamic banks to further improve. In addition, as the study finds no correlation between the ratio and efficiency scores, it proposes to use a combined measure of ratio analysis and efficiency analysis for a comprehensive assessment of bank performance.
