Jio Fiber Internet

Ladies and Gentlemen, I have been using Jio Fiber 100mbps since last 3 years. All of a sudden in last 2 months there has been some stability issues in regards to internet speed, got the box changed but still issues occur. And since I primarily work from home, need something with stable connection. I am getting inclined towards airtel xstream fiber. Please suggest how is it working for you all? I am planning to get 200mbps plan.
