Remote or hybrid workers, would you rather work a 4 day week on site, or WFH completely for 5 days a week, for the same pay?

I know this will vary a lot, so hypothetically let’s say you currently WFH/work remotely at least 3 days a week. Your commute to work takes an hour max (door to door) each way. If you were given the choice of a 4 day week working onsite, or a 5 day week WFH (or as many days as you’d like) for the same pay, which would you choose?
