Relative to Competition
The Sikorsky and Boeing engineering team are currently busting their butts getting the Defiant to First Flight. And they have my respect. But they more than anyone else the SB>1 probably respect and recognize the groundbreaking FVL schedule achievements of Bell. The little guy in the FVL competition with Goliaths.

Your missing the point. The 280 is an improved tiktrotor design with increased agility and fixed engines with all of associated benefits (minimizing surface heating, improved firing arcs, simpler engines, etc...).. Itt was never meant to be significantly faster than the V-22, but was meant to have significantly better hot/high performance. The time to max speed is only relevant with respect to showing the maturity of the technology and technical prowess of the developing organization.
The 280 program has done what it needed to do. It has already demonstrated superior performance and lower technical risk as compared to the SB-1.

Long List of Achievements
The list of V-280 achievements go on to include major reductions manufacturing and maintenance costs. Not just promises, but validated by applications of similar technology on Bell commercial products.
In my opinion however the most amazing V-280 achievement was meeting a very aggressive customer program schedule that few in the industry thought possible. Not even the “Dream Team” comprised of the two largest defense contractors in the world came close to what Bell achieved in 5 years.

I think we will see the V-280 as the winner of this program. Higher speed, longer range and list risk. Well done Bell.
Wonder what the military designation will be? UH-65? MV-25?

Maybe they should dispense with gear doors like on the 737 and other aircraft. Sometimes they are more problems than they are worth.
V-280 to Pause
So it appears the V-280 program will finish its demo effort before the SB-1 even flies:

How embarrassing for Sikorsky-Boeing, especially when it was Sikorsky who blocked Bell’s request to slip the original demo schedule.

A 737 flys a lot faster than 280 Kts and does not require separate actuated doors over the wheels. You just design it properly to minimize buffeting.
300 Kts Sans Doors Sansanhedral :-)
Perhaps the added drag from not having doors is not the negative the aero guys thought? So for production the V-280 can dispense with actuated doors and save cost, weight, and improve reliability.
FYI. The reused Cessna Citation gear used on the V-280 also did not have actuated doors.
