And my point is that any scenario is exotic when it's unexpected. Using your 25 year timeframe - something will happen and one of the choices will be a clear winner when viewed 25 years from now. Nobody knows which. The best choice is to pick the one that puts you in the best situation the earliest or that one that gives you most options. Currently AC wins on both.
Again, using your scenario; the AC pilot upgrades after 2 years while the WS pilot upgrades after 9 - how many years does it take for the WS pilot to close the gap? According to you she never does and finishes her career 16% behind. Furthermore, for at least the last half of their respective careers the AC pilot has the WB option and other postion options. AC has 43 (or is it 46, can't remember) biddable pilot positions with the current fleet. The flexibility to bid senior for pay or junior for schedule at 4 different bases across all those positions is nothing to sneeze at when considering a 25 or 30 career.
Sure, if you restrict your analysis to the 737 WS comes relatively close to AC but that's an artificial restriction. In the real world bidding WB for a few years before retiring greatly increases the differential doing it even earlier makes the difference significant.
It's like saying the ham on the Hilton buffet is better than the ham on the Crowne Plaza buffet. That might be true but the Crowne Plaza buffet also has roast beef and turkey.
