Talking about AirFiber in general, Jio AirFiber Plus (C6 UBR antenna based ODU) connections provides even lower ping like 5-10 ms on their AirFiber connection. But the stability is not great or equivalent like Jio optical fiber. You can check our forum user reviews to confirm the same. Similarly, any AirFiber service has their own cons, one major con is the 1 TB data cap compared to 3.3 TB on Fiber.
Btw bro, as you have
already got Airtel Fiber (optical fiber) feasibility on both your office and home, I don't think you should care much about the AirFiber stability. I would say, better to disconnect the Airtel AirFiber connection as soon as your already paid term is over, unless you want to experiment something on both connections side by side (and having extra money to spend every month – J/K

). It doesn't make sense to keep both Fiber & AirFiber from the same company at the same location considering they are generally connected to the same nearest OLT/tower.
AirFiber can not and would never match Fiber in terms of stability/reliability. It's just a cost cutting product to get returns from the 5G investment. Once towers get overloaded, both the operators would again shift focus towards optical fiber. This is not only my opinion but also the whole telecom industry's prediction.
