Do you race? If so, gearing range and spacing matters. I’d put together a spreadsheet looking at the mechanical advantage of each of the gear combinations within each ring.
Similarly, while I enjoy my Di2 on my endurance bike (Roubaix), the speed of shifting of the cassette in my AXS on my racing bike (S-Works Tarmac) has been great for both racing and spirited group rides. I’m not sure if there are similar differences between Rival and Force, but it may be worth investigating if this is important to you.
