Sunday is pretty much the worst day of the week to use metro because it has the lowest number of people trying to get places, so the metro is frequently running degraded service to allow for extra maintenance, and there is much less traffic to slow down an Uber. I would pretty much never consider taking an Uber over taking the metro from 7am-7pm on weekdays because it would invariably be slower and more expensive.
