Boeing had to concentrate on the B787 for years longer to fix the massive infrastructure screw that it was. The next project was to modernize the 777 which has eaten the lunch of the A330, A340, and A380 series.

That said, Airbus made an excellent decision to upgrade the A320 during a time where Boeing did not have the resources to properly respond.

The win allowed Airbus to expand sales by number if not by actual dollar amount. It really was an interesting move. Pride (we sold more airplane) -vs- money (the government will save us)

Boeing pushed too hard and ended up with the 2 737 Max disasters which played right into the hands of Airbus.

Those accidents, and Boeing's anti-Bombardier attack, which proved absolutely disastrous pushing the C series directly to Airbus have damaged Boeing's credibility as well as the FAA's pulling the USA's reputation along with it.

All that said a A -vs- B conversation can be a lot of things.
The Neo beats the Max dollar for dollar. You would stick with the Max if you have a majority 737 fleet. Honestly, the Max was a band aid solution for a long term problem. The NMA will likely annihilate anything Airbus has to offer, but that is 3-5 years off
