(Not the original person but I can give my two cents) I've been exclusively pumping for about 4 months. My daughter was born at 35w and struggled heavily to latch, and got to the point where she would just scream bloody murder at my boob. Pumping is miserable for me, but I'm counting down the days and already phasing out/supplementing with formula. The pitcher method works for us because our daughter goes to daycare, and I essentially need to prep a full day's worth of bottles the night before. Using the pitcher, I can dump all my pumps throughout the entire day into one container, and pour at night/in the morning for daycare. When we didnt use the pump method, we routinely had too many bottles stacked in the fridge that we would get mixed up (what was pumped today vs yesterday), and had a harder time with "first in first out" milk usage.
