I certainly wouldn't spend the money for a soon to be outdated 11 speed electronic group this year.
I've read a lot of drivetrain noise complaints from force axs owners. The new chain is not to blame, it's quiet on a Campy 12 drivetrain. The noise apparently comes from the cassette.
Right now, force axs is very high priced unless it's on a prebuilt bike. I bought two campy chorus 12 groups for less than the typical asking price for a force axs group. The shifting is great.
