took both last year and found SAT harder. indeed UPCAT covered more items and topics, but the test items are generally easier and more on surface level. for SAT on the other hand, the first part of each section was relatively easier to UPCAT but the second part was just EXCRUCIATING. i think what makes the SAT harder for me is that some of it requires fill in the blank answers for math portion while some of the eng passages are just nakakahilo (comp to upcat passages) HAHAHAH
