Poco F1 is absolute beast and game changer because of its Snapdragon 845 processor. All other brands are offering same processor above 30k. Camera doesn't disappoint be it front or rear. I compared the images with One plus 6, Op6 selfies are more clear but portraits clicked by poco are just amazing.
4k mah battery is just awesome, it lasts for whole day with normal usage. I bought this for PUBG and it performs really well with extreme frame rate, it neither heats nor eats all the battery.
If your budget is 20k then go for it, dont hesitate.
