Why we choose Nordic ic for Ble application?

Why we choose Nordic ic for Ble application? what is batter in that ic then another ble ic like TI, ESP32 etc.

Well there are some facts on the paper given by each manufacturer. And then you need to know what device are you building;) There are like hundred criteria and some of them will be more important for you and some less. Starting from cost to packages available through power consumption, performance, available interfaces and HW "acceleration" blocks, radio stack(s) availability, features, licenses, SW support...

This is really strange question;) I guess majority of people here will tell you that Nordic nRF52 is superior to its direct competition in majority of these points, that's why are we all here. However if you ask TI or Silabs or Cypress or CSR or NXP or ST or Thoshiba or whoever else they will tell you they are better. That's business;) Only assembling fact sheets and evaluating from YOUR point of view will give you some hints and if you REALLY want to do it right then you should buy dev kits from 3-4 "short listed" candidates and evaluate major points (such as performance, SW support, BLE stack performance, power consumption) yourself. Nice 2-4 months project! Good luck.

(btw. you seems to be comparing motorbikes with cars and maybe with trucks, nRF5x chips are pretty different target then ESP32 with WiFi and multi-core MCU...)
