Need advice! COVID19 semester

Hello! This semester due to COVID19 my university along with several others are allowing pass/no pass grades. This spring semester I was studying abroad and of course needed to travel back to the U.S. I withdrew (W) from one class this semester. In my other classes I received A, A-, and B-. Should I take a Pass § or B-?My deadline to decide is tomorrow. My cumulative GPA is very high and the B- would lower it slightly. But would it be worse to have a semester of a W, P and only two letter grades even if they are A and A-? Really cant decide. I am a sophomore and interested in difficult grad programs. Should I go with a Pass or a B-? How will the pass be viewed? I have gotten mostly A’s and few B+ throughout college.
