Buying my first phone under 20k !! Suggestions pls😇

Guys I just turned 18 and joining my college next month. I am buying my first phone in the upcoming Amazon Prime day or Flipkart GOAT sale. I don't game heavily, But I do game somewhat. I want a phone which is great for day to day productivity. And most importantly I want it to last for next four years. Please recommend guys, currently I am leaning towards CMF phone 2 pro.
