How Do you guys watch Live TV Channels on your Smart TV?

I have cut the cord and now I don't have any cable subscription. I bought a firestick from this amazon festival sale. Using some default apps to stream content and some third-party apps to watch live sports (https://firestickapps.org/live-sports-on-firestick/) on my smart tv.
I am really happy now and I have saved a good amount of money by cutting the cable. I just want to know how do you guys watch your favorite content on Smart TV? 
Also, suggest some good apps for my firestick.
